/* ============================================================================
   PMF FOUNDATION — CONSOLIDATED ("ATLAS + grafts")
   Appended verbatim to content/assets/css/style.css. This is the design
   constitution: Atlas's editorial architecture (numbered section index,
   hairline rule vocabulary, sidehead grid, modular type) with the seven
   grafts the bake-off judges named unanimously.

   LAYERING CONTRACT — read before editing:
   ---------------------------------------------------------------------------
   PAGE scope   rule/kicker tokens derive from --foreground via color-mix so
                they self-correct in light and dark. SURFACES are literals,
                hand-written in all three branches (light :root, both dark
                branches), because the oklab mix desaturated the cream to grey.
   INK scope    (.stats-stripe / .cfs-cta / .tickets-section / .atlas-band) is
                ALWAYS dark in both themes. style.css flips --foreground and
                --background back to LIGHT values inside those bands at
                specificity (0,2,0); rather than fight that we give the bands a
                MODE-INVARIANT ink vocabulary (--ink-*, --on-ink-*) and re-point
                every derived page token at it in one block.
   LIGHT-ISLAND style.css's flip fires on FIVE selectors, not three: the two
   scope        extra ones (.cfs-form-section, .partners-form-section) are pale
                coral PANELS, not ink bands. They get the mirror treatment —
                surface literals pinned to their LIGHT values — and no
                atmosphere. Miss this and a surface-reading element inside them
                paints dark-on-dark in dark mode.
   NEVER        redefine --foreground / --background / --card / --border /
                --muted-foreground / --white in this file's band scope: the
                style.css dark-band block outranks it and the band inverts.
   ALWAYS       write dark overrides under BOTH [data-theme="dark"] and
                @media (prefers-color-scheme: dark){:root:not([data-theme="light"])}.
                Verified by scratchpad/parity.js — they must be verbatim twins.

  /* ---- GRAFT 1 — dark-band atmosphere (Voltage) ------------------------
     The bloom must be SMALL AND HOT, not broad and dim: a broad low-alpha coral
     wash over black only makes maroon mud. A tight high-alpha core falling to
     pure ink by ~70% reads as light spilling into a black room.
     The coral bloom (top-LEFT) and the ember counter-glow (bottom-RIGHT) are
     deliberately kept spatially disjoint — they die out around x≈36% and
     x≈76% respectively — because where crimson and orange overlap over black
     they mix through a dead olive-brown, which is the amateur-gradient tell
     the judges named in Voltage.
     Radii are min(px, vw) — NEVER percentages of the band box, and never bare
     pixels. Percentages made the 220px stats band modest and the tall tickets
     band a 1,400px smear. Bare pixels then broke the other way: a 760px bloom
     on a 390px phone IS the broad low-alpha wash, so the whole band went muddy
     maroon and the two glows overlapped through olive-brown. Capping against
     the viewport keeps the light source the same proportion of the band at
     every width, and keeps the two glows disjoint. */

/* GRAFT 5 — the vertical container-edge hairlines (Lumen).
   Atlas had a rich HORIZONTAL rule vocabulary and no vertical frame, so its
   empty sidehead column read as leftover space rather than intentional margin.
   Painted as two background layers rather than as ::before / ::after, because
   Atlas already spends those pseudos on its opening horizontal rule on three
   of these very sections.
   Carried by the SECTION, not by .container: a container-carried line stops
   where the content stops, leaving a hairline that starts and ends in mid-air
   — the exact "orphaned vertical rule framing nothing" the judges marked
   against Lumen. On the section it runs the full band height, so consecutive
   light planes join into one continuous frame and the ink bands cut it. The
   layers are placed at the shell edges with calc() so they land on the content
   column, not on the section's own (full-bleed) box.
   Gated at 1280px: below that the shell touches the viewport and the lines
   would sit on the screen edge. Light planes only — the ink bands are already
   framed by their own lit edge. */

   CONTRACT NOTES
   • Every dark value is written under BOTH [data-theme="dark"] and
     @media (prefers-color-scheme: dark){:root:not([data-theme="light"])}.
   • style.css nukes ALL animation under prefers-reduced-motion, so every
     scroll-driven effect is declared with its RESTING state as the base rule
     and the keyframe only moves it away from there. Reduced motion therefore
     lands on a correct, finished nav — never a half-applied one.
   • The mobile panel uses visibility/opacity rather than display, so it is
     removed from the tab order without depending on a transition running.

   2. NAV — THE LOCKUP
   The identity is TYPE, not a bitmap. The shipped PNG contributes only its
   bulb (windowed in §0); the name is set in the site's own face so it can be
   tracked, weighted, recoloured and — critically — given a second optical
   size for the phone.

   TWO OPTICAL SIZES, one construction. Both are a wordmark line over a
   dateline line, flush left, with the bulb set to the block's cap-to-baseline
   height so the mark sits INSIDE the type's optical range instead of
   overhanging it (the old lockup ran a 34px bulb against 12px type — 2.8x,
   which is why the mark read as the logo and the words as a caption).

     < 1120px   PMF, 23px/600 caps          cap height 16.1px   bulb 26px
     >= 1120px  the full name, 15.5px/600   cap height 10.9px   bulb 22px

   The switch is at 1120px, not at the 900px layout breakpoint, because 900px
   is exactly where the five nav links arrive: measured, the full-name lockup
   plus caps links plus the ticket pill overruns an 820px content column.
   1120px is the first width where all three fit with slack. Note the
   consequence: below 1120 the lettermark is the LARGEST type in the bar, and
   above it the wordmark is still ~30% taller than a nav link. The identity is
   never the smallest thing on the masthead again.

/* ==========================================================================
   1. THE PORTRAIT SYSTEM  — .pf
   --------------------------------------------------------------------------
   Twelve portraits arrive from twelve sources: 400px to 2316px, all square
   LinkedIn-style headshots, every one with its own white balance, backdrop
   and exposure. Four rules turn them into one curated set: crop, framing,
   grade, and how the plate meets the page.

     CROP    aspect-ratio 4:5 (`--pf-ar`). Portrait, not square: square reads
             as an avatar, 4:5 reads as a plate. Every source is 1:1, so the
             crop takes 10% off each side — never off the head.
             Modifiers: .pf--1x1 (board thumbnails), .pf--3x4 (dense grids).

     FRAMING One grade is not one system. Grading twelve sources to a single
             temperature makes them look printed by one lab; it does nothing
             about the fact that they were SHOT by twelve different people —
             head at 29% of the frame in one, 56% in another; eyes at 22% in
             one, 42% in another. Framing is normalised per portrait with
             `--pf-zoom` / `--pf-ty` (values and method below).
             `object-position` cannot do that job here and `--pf-y` is inert:
             every source in the repo is square (400-2316px) and the plate is
             4:5, so `cover` uses the full height and crops WIDTH ONLY. --pf-y
             is kept as the safety value it is, and becomes load-bearing the
             day a non-square source is added.

     GRADE   A WARM DUOTONE, not a desaturation. Three of the twelve sources
             are already monochrome and the other nine carry a different cast
             each — one shot under blue stage light, one against a pink wall,
             one on black seamless. Any partial desaturation leaves that split
             visible, so the grade goes all the way: grayscale(1) then a sepia
             re-tint pulled onto the system's warm axis, then a contrast lift
             to recover the flattening. Twelve sources, one temperature.
             Hover/focus releases to full colour — curated at rest, alive on
             contact. The featured plate opts out (.pf--colour): the keynote
             stays in colour at rest, which is the hierarchy device that makes
             the wall an opener plus an index rather than a uniform grid.

     MEETING The plate carries a 1px inset hairline in --rule-hair, the same
     THE     line the foundation draws between sections, so a photograph
     RULES   terminates the way a rule does. Radius --r. No drop shadow: the
             foundation's elevation belongs to cards, and a photograph that
             floats competes with the display type. The plate also paints the
             veil (--pf-veil-*) — except on the featured plate, where plate
             and photograph are different boxes and the veil moves onto the
             `picture` so it ends at the photograph's own edge. See §2.

     Reuse the SYSTEM (.pf, .pf--1x1, .pf--3x4, .pf--colour) verbatim on
     /speakers/ and /board/. Do NOT copy the per-portrait framing values —
     those are measured against this page's 4:5 plate and are scoped to it.

     varies between the twelve is how big the head sits in its own square and

/* ---- PER-PORTRAIT OPTICAL FRAMING ------------------------------------
   Twelve sources, twelve different shoots. Measured off a rendered guide
   sheet (eyeline + crown + shoulder rules struck across every plate), not
   calculated: at --pf-zoom 1 the head ran from 29% of the plate (Ania) to
   56% (Célina) — a 1.9x spread — and the eyeline from 22% (Lax) to 42%
   (Nick). That is what made eleven curated portraits read as eleven
   different photographs.

   Values below pull the set toward head ~50% of plate and eyeline ~0.37.
   Zoom only ever goes IN: every source is square and the plate is 4:5, so
   the vertical dimension is already fully used and there is no crop to give
   back. The set therefore normalises toward its TIGHTEST member, and the
   ceiling on each value is the source's own resolution, not taste —
   Lax and Beatrice are 500px, Niclas 478px, Pauline 400px, so their zoom is
   capped where the plate would start to go soft rather than where the
   geometry would ideally land. Sources already inside the band carry no
   value at all.
     f' = 0.5 + (f - 0.5) * zoom + ty     (transform-origin is the centre)
     |ty| <= (zoom - 1) / 2               (or the plate edge shows through)

   SCOPED TO THE WALL ON PURPOSE. The .pf SYSTEM is reusable anywhere; these
   VALUES are not. They were measured against this wall's 4:5 plate, and a
   --pf-ty tuned for 4:5 can exceed the (zoom-1)/2 slack on a .pf--1x1 board
   thumbnail and show the plate edge through. Any other surface re-measures
   against its own ratio. */

/* ---- the featured plate — caption INSIDE the frame -------------------
   A second photographic register: the eleven read as an index, this one
   reads as a poster. The ink foot is deepened so the on-ink type clears
   AA against any pixel of the photograph underneath it. */
/* THE FEATURE IS NOT EXEMPT FROM THE SYSTEM.
   Round one let the featured plate off its 4:5 so it could fill the 2x2 cell:
   540x870 = 0.62 against the tiles' 0.80. Every source is square, so `cover`
   at 0.62 threw away 38% of the frame's width where the tiles throw away 20%,
   and rendered the face at ~2.7x tile scale. That is not "the same system,
   larger", it is a square photograph stretched into a tall box — and it broke
   on the one image the page is judged by.

   The fix separates two things round one had conflated: the PLATE (the cell
   the layout hands you) and the PHOTOGRAPH (which owes the system its ratio).
   The plate keeps filling the 2x2 cell and is backed in ink; the photograph
   sits at the top of it at the tiles' exact 4:5; the ~190px of ink left below
   becomes the caption plinth. Crop 38% -> 20%, scale 2.7x -> 2.1x, and the
   poster register survives because the type is still on ink inside one frame.

   The scrim moves off the plate and onto the PICTURE, so it ends exactly at
   the photograph's own bottom edge no matter what height the cell resolves
   to — no px guess about where the joint falls, and it degrades to identical
   output on mobile where plate and photograph are the same box. */

   the only stretch on the page over the ~800px budget. The manifesto sits in

   go up to display size and each one gets a coral segment lit on its rule, so
   the row reads as three ruled statements rather than three paragraphs.

   3. THE LOGO SHEET — "Speakers from"
   --------------------------------------------------------------------------
   Eleven employers, de-duplicated from the speaker data, plus a twelfth cell
   that says what the wall is NOT. Twelve cells divide cleanly by 2 / 3 / 6,
   so the sheet closes at every breakpoint with no orphan row.

   OPTICAL SIZING. Cap height, not bounding box. The eleven marks run from
   1.36:1 (the NVIDIA badge) to 6.78:1 (vector8); set to one height the badge
   reads as a postage stamp and vector8 reads as a banner. Each mark gets a
   height tuned so its perceived AREA and stroke weight match the set — wide
   wordmarks come down, square badges go up. Values were set against a
   rendered contact sheet of all eleven, both grounds, not calculated.

   COLOUR. Every source is already black or near-black (#000 / #221E1C), so
   light mode needs no filter — only an opacity that seats the sheet behind
   the type. Dark mode inverts. Deliberately NOT flattened with
   grayscale()+brightness(0): TWINT is a filled plate with a knocked-out
   wordmark and collapses to a solid blob under that treatment (verified).

   Contract notes carried over from the foundation header:
   • .atlas-band is an INK scope: --foreground/--card/--muted-foreground are NOT
     re-pointed there by style.css, so anything inside the band must name the
     mode-invariant ink vocabulary (--on-ink*, --ink-*) explicitly. A band
     element that reads --foreground paints white in dark and near-black in
     light — on an always-dark ground.
   • Company logos are single-colour near-black SVGs. In PAGE scope they need
     the dark-only inversion (re-declared here under both dark branches because
     this file renames the class). On the ALWAYS-dark band they need the
     inversion in BOTH themes.

   P1.1  MASTHEAD (01) — the arrival
   Three faults were repaired here at the root:
   • The section had no height. Its own padding rule never applied: style.css
     carries `main > section:first-child { padding-top }` at (0,1,2), which
     outranks a class, so the masthead silently ran on the generic 84px. Sized
     off the id from here on, which no page-scope rule can outrank.
   • The display line filled 495px of an 826px column. The column is the Atlas
     sidehead split and must NOT be narrowed — /speakers/ section 03 sets its
     heading on the same left edge, and moving one of them breaks the only
     alignment the split exists to guarantee. So the TYPE grows instead, to a
     piece-local display size that runs the headline to the spine edge.
   • The numbered index floated between the headline and the lede, aligned to
     nothing. It now HANGS off the H1's cap-line: same serif in both, so the
     cap sits 0.1993em below the line-box top of each, and the offset is one
     subtraction. It is also un-stuck here — sticky in a 630px masthead
     detaches on the first scroll and the alignment evaporates.

   PIECE P2 — THE SPEAKER FEATURE PAGE          templates/speaker.njk
   ==========================================================================
   The page a speaker forwards. It is built as a magazine feature on the
   foundation's own vocabulary — nothing here invents a token:

     · masthead        the hero's lit cream ground (coral top-right, ember
                       left, dot field) re-used at page scale, opened by the
                       hairline rail the dateline already established.
     · dateline        the .stats-stripe table, moved to paper: hairline
                       columns, small-caps labels, the accent gradient on the
                       one numeral that matters (the start time).
     · reading zone    a numbered sidehead over a two-column spread; the prose
                       is pinned to a 46ch measure so the 135-character line
                       the old page shipped can never come back.
     · deck / drop cap every abstract opens on display type. Paragraph one
                       becomes a serif deck when it is short enough to carry
                       it; when it is not, the body takes a coral drop cap.
                       One rule, two outcomes, no page left as a wall.
     · the margin      the marginal column, and the thing this revision exists
                       for. It was previously occupied by the coda alone, which
                       is content-gated and fired on three of twelve pages, so
                       nine pages rendered a 360px empty column for the height
                       of the section. It now leads with two members that exist
                       for every speaker on file — a hard-cropped duotone of
                       the portrait and the session's own facts — and takes the
                       co-speakers and the coda as bonuses. The photograph is
                       the elastic member, so the two columns start and finish
                       on the same line at every abstract length.
     · density         and where that is the wrong composition — a single
                       sentence, or no abstract at all — the spread is not run.
                       See DENSITY in speaker.njk.
     · coda            an abstract of three-plus paragraphs that closes on a
                       short one gets that closing line lifted out under a
                       gradient rule, in the margin or at the foot of the
                       article depending on which column needs it. It is the
                       organiser-written abstract's own last sentence,
                       presented as such — never in quotes, never attributed,
                       because nobody said it aloud.
     · end action      one .atlas-band: the ticket, the schedule, and the two
                       neighbouring speakers.

   DARK: every colour here resolves from a token that already has both dark
   branches in style.css (surfaces, rules, --link, --kicker-ink) or from the
   mode-invariant ink vocabulary inside the band. The two explicit dark blocks
   at the end are verbatim twins — see the note there.

   BAND CONTRACT: .atlas-band is NOT in style.css's light-flip list, so inside
   .sp-cta --foreground / --background / --card / --muted-foreground must never
   be read. Only --on-ink*, --ink-*, --primary-bright and the auto-repointed
   --accent-grad / --kicker-ink / --link appear below that line.

     Twelve portraits, twelve photographers, twelve studio backgrounds: grey,

     controlled surface on the page — and in dark mode a white studio wall is
     the brightest block on the whole document, out-shouting the headline.
     Mapping every photograph between one shadow tone and one highlight tone
     fixes both at once: the hue is unified to the warm-cream ladder and, more
     to the point, the RANGE is compressed, so the brightest pixel any portrait
     can produce is the highlight tone rather than paper white.
     Literals, not color-mix off --foreground/--background: those two must
     never be read inside the ink band (see the BAND CONTRACT above), and this
     component has to stay safe to reuse anywhere.
     Light: floor a warm near-black, ceiling just under the page ground, so the
     plate reads as an object on paper rather than a hole in it.
     Dark: ceiling dropped to 70% L — relative luminance 0.44 against the

   Mackenzie's and Celina Nim's, caught on a seven-up contact sheet of every

   a stray graphic. It also adds ~60px of mass to the identity column, which is
   half of the void the masthead used to open under the LinkedIn pill.
   TWO — optical sizing. --logo-h is written by the template from the asset's

   the other nine rendered a ~360px empty column for the height of the section.
   The margin now leads with two things that exist for every speaker on file —
   a photograph and the session's own facts — and takes the coda and the
   co-speakers as bonuses when the content happens to carry them.

   7. DARK — both branches, verbatim twins (scratchpad/parity.js)
   Almost nothing needs restating: every surface, rule and link above resolves
   from a token style.css already flips, and the band runs on the invariant
   ink vocabulary. These are the three that do not self-correct:
     · the portrait ring — --rule-hair is a color-mix off --foreground, which
       lands near-white in dark and then sits under a photograph that is often
       near-white too. Pinned to a fixed low-alpha cream so the plate keeps an
       edge against light and dark photographs alike.
     · the masthead wash — the two glows are rgba literals, so they do not flip.
       Over cream the coral carries at 0.095 and the ember needs 0.105 to be
       seen at all; over the ink ground that ember turns the corner sludgy while
       the coral all but disappears. So coral goes up and ember comes down, and
       the pair stays as spatially disjoint as the foundation demands.
     · the logo — style.css inverts .company-logo to near-white in dark, which
       reads a stop brighter than the same mark does black on cream.

/* ============================================================================
   PIECE P3 — THE SCHEDULE PAGE  (/schedule/)
   Appended to content/assets/css/style.css after the PMF FOUNDATION block.

   Reads the foundation's vocabulary, adds no new primitives: the numbered
   kicker, the hairline rule set (--rule-hair / --rule / --rule-strong), the
   warm surface ladder (--surface-0…-card), the ink band atmosphere
   (--band-image / --band-edge / grain / dot field) and the outlined pill are
   all inherited. What is new here is a ROW TIER SYSTEM — a day has a shape,
   and the page should show it:

     keynote          ink slab, portrait, display serif   — the headline act
     panel / lightning filled full-width band
     talk             lane card, portrait, hover-lift
     announcement     lane card, dashed — nothing confirmed yet
     registration /   one ruled line, no box: the eye skips them
     ceremony / break

   ACCESSIBILITY REPAIR (the named defect):
   .sched-pill painted --primary-foreground (white) on var(--stage). In dark
   mode style.css lightens the stage accents to hsl(188,55%,50%) and
   hsl(285,55%,66%), so the pill measured 2.49:1 and 3.02:1 — both fail AA
   badly. Fixed structurally rather than by nudging a lightness: every stage
   marker is now TINTED GROUND + ACCENT TEXT + hairline border, a form that
   cannot invert, and the accents themselves are retuned onto the house axis
   (deep petrol / burnt ember instead of cyan / violet). Measured, this file's
   values, text on its own 12% tint:
       light  stage-1 6.95:1   stage-2 5.63:1
       dark   stage-1 5.20:1   stage-2 5.10:1
   Colour is never the only channel: the chips are literally labelled
   "Stage 1" / "Stage 2", and the lane header names both columns.

/* ==========================================================================
   P3.0 THE SURFACE LADDER — the tier system, calibrated in BOTH modes
   --------------------------------------------------------------------------
   The row tiers below (slab > band > card > ground) only existed as a light-
   mode idea. Measured against the rendered pixels, the old build read:

       LIGHT   ground 1.00 · card 1.03 · band 1.07 · slab 17.80
       DARK    ground 1.00 · card 1.26 · band 1.21 · slab 1.03–1.07

   In light the two middle tiers were not surfaces at all — which is why the
   panel and the lightning block vanished and the afternoon died. In dark the
   whole idea INVERTED: .atlas-band paints --ink-900 (rgb 17,13,11) in both
   themes, and the dark page ground is rgb(29,24,22), so the loudest tier in
   the system was the DARKEST — and therefore the quietest — object on the page.

   The rule the ladder now follows, stated once and applied in both themes:
   ---- THE KEYNOTE IS THE SURFACE FARTHEST FROM THE PAGE GROUND. ----
   On paper that means near-black (a printed plate). At night it means LIT —
   a warm ember panel raised well above the ground, with the crimson bloom and
   the ember counter-glow amplified so it reads as a light source rather than
   as a hole. One identity, two calibrations.

   Two mechanical notes, both of which silently defeat a naive fix:
   • --band-image's LAST layer is an opaque linear-gradient, so it paints over
     background-color. Re-pointing the colour alone changes nothing; the image
     has to be re-pointed too. Hence --slab-image.
   • #schedule's own ground is DARKENED in light (surface-2, not surface-0).
     --surface-card (99.4%) is lighter than --surface-0 (97.6%), so a card can
     never be pushed further from a near-white ground — the ground has to come
     down to meet it. In dark the ground stays surface-0; there the ladder
     already ran the right way.

   Measured targets (verified by pixel probe, see p3surf.js):
       LIGHT   ground 1.00 · card 1.11 · band 1.25 · slab ~13
       DARK    ground 1.00 · card 1.26 · band 1.45 · slab 1.73–2.10

   rounded white cards with 1px borders, 80px circular full-colour avatars,
   pink --coral-light slabs where the rebuilt pages use lit ink bands, a
   720px column stranded in the middle of a 1200px shell, and a stacked
   page opener where every rebuilt page uses the two-column editorial split.

   This overlay closes those seams. It invents nothing: every device below is
   the Wave 1 / foundation vocabulary applied to the pages that missed it.

/* THE WEAKEST SOURCE SETS THE PLATE.
   The board's three portraits are not the lineup's twelve: Tanja and Yariv
   arrive at 800px, Cosima at 200px — the only source of her that exists, and
   inventing a better one is not on the table. At the full shell the plate ran
   355px wide, i.e. 710 device pixels at 2x DPR from a 200px file, a 3.55x
   upscale sitting at equal size beside two sharp plates on the page's opening
   beat. Read at 2x side by side, it was the one thing on the page that looked
   like a mistake.
   The plate is therefore fixed at 300px above 1060px and the surplus is paid
   out as gutter (space-between), which keeps the wall spanning the shell edge
   to edge instead of stopping short of it. Cosima drops to 2.0x CSS / 600
   device px and closes most of the gap; the wide gutters read as air, not as
   a short row. Below 1060 the tracks go back to 1fr, where they are already
   at or under 300px. The remaining softness is an ASSET gap, reported.
   Do NOT add --pf-zoom to the weak plate: zoom resamples further and makes
   exactly this problem worse. */

   K. HANGING THE INDEX — the numbered kicker on the display cap line
   MEASURED, not guessed. The foundation's split makes the sidehead kicker
   position:sticky at top: nav + 28px = 96px. On a page's FIRST section the
   flow position is nav + 16px = 84px, so the kicker is already stuck at load
   and hangs 12px BELOW its own row — the index and the display line start at
   different heights on every page whose opener is a first section. Probed at
   1440: label top 96 vs h1 top 84 on /board/, /venue/, /partners/,
   /call-for-speakers/, /impressum/, /privacy/.
   /speakers/ solved exactly this by going static and paying the cap-line
   offset in padding instead. Same construction, same arithmetic, reused here:
   DM Serif Display sets its cap line 0.1993em below the top of a 1.06 line
   box, so matching a 22px numeral to an --fs-h1 display line is one
   subtraction — and it re-derives itself if the display size changes.
   Second sections keep their sticky index: their flow position is far below
   the threshold, so nothing is pinned at rest.

   THE BACK HALF, DESIGNED — and the close, built.

   The verdict on the home page was that it stops being designed after section
   01. Measured: lineup 2329px of designed content, then manifesto 585, logo
   sheet 458, tracks 696, venue 465, tickets 1092 — of which 440px was an empty
   rectangle. Four of those five shared ONE failure: the two-column editorial
   header with its right column empty, one shallow row of copy, then dead
   bottom padding. And the sequence terminated in a ticket module that was a
   heading, a pill and a naked 400px <iframe> rendering as the same untreated
   cream slab in BOTH themes.

   This overlay closes that. It invents no vocabulary: every device below is
   already on the page, taken from the lineup wall and the logo sheet — the two
   blocks that were judged to work — and applied to the sections that missed
   it.

     FRAME     .atlas-split · .atlas-rule · .atlas-spine · .atlas-breakout
     HEADER    .atlas-kicker (numbered) + .atlas-head (heading | lede)
     ACCENT    em / .atlas-accent — the crimson→orange display gradient
     CELL      hairline-topped column: rule, serif numeral, caps kicker, copy
     RAIL      hairline-topped closing row: one line of copy + .atlas-pill
     ACTION    .btn-primary (solid) · .atlas-pill (outlined secondary)

   Page-scoped prefixes carry LAYOUT only, never a second visual language:
     .mf- manifesto · .lw- logo sheet · .tr- tracks · .vp- venue · .tk- tickets

   The page ran six different padding pairs: 144/96, 64/52, 64/116, 116/116,
   68/68, 112/112 — close to a system, not one. There is exactly one scale:
   --section-y, top and bottom. Sections that open with the container hairline
   pay for that hairline's gap out of their own top padding, so a ruled section
   and an unruled one still measure the same overall.
   Scoped to the home page's own sections (.tracks-section.atlas-split, never
   bare .tracks-section — /call-for-speakers/ reuses that class and is another

   G. 06 · TICKETS — THE CLOSE
   The conversion moment was a heading, two sentences, one pill and a naked
   <iframe height="400" loading="lazy"> with no styled empty or loading state
   and no theme handling: cropped in both themes it was the identical cream
   slab with a drop shadow. No tier, no price, no what's-included, no capacity.
   The Atlas hairline vocabulary never touched it.

   It is now the page's densest block after the wall:
     · the same numbered kicker and two-column header as 01–05, with the accent
       gradient firing on the heading (it was absent here);
     · a hairline RATE GRID — the three real Eventfrog categories at their real
       gross prices, with ONE footnote carrying the organiser prices;
     · WHAT'S INCLUDED as a hairline list plus the honest fine print, and the
       link-out failsafe sitting with it, above the embed;
     · the checkout MOUNTED: captioned frame, skeleton behind the iframe, a
       stalled state after 7s that names the likely cause.

   INK SCOPE. Everything below lives inside .tickets-section, where --foreground
   / --card / --muted-foreground are re-pointed to light-on-ink values in BOTH
   themes. Rules read --ink-rule / --ink-rule-strong, text reads the --on-ink

   as a sheet of PAPER laid on the ink band, with its own local palette written
   as literals (the band re-points every --surface-* token to ink, so a paper
   object inside it cannot read them). The band's own lit top edge is repeated
   on the frame, which is what makes the assembly read as a designed object on
   ink rather than a hole punched in it.
   NOT transformed or scaled: the iframe carries allow="payment" and is
   interactive, and a transform would wreck its hit targets.

   H. HERO — three defects on the page this piece owns
   1. .hero-carousel measured x=90 → 366 inside a container running 24 → 366:
      66px off the left rule and flush right, because the desktop card rule
      (justify-self:end + a fixed max-width) was never gated to desktop.
   2. The carousel dots were 24x24 — the project's own CLAUDE.md mandates
      >=44x44 touch targets, and they are the carousel's only control. They are
      now a segmented hairline rail: full-width buttons 44px tall, each marking
      its slide with a 2px rule that lights coral when active. That also
      retires the dot-row widget idiom.
   3. The card was one of the two drop-shadowed slabs bookending the page. The
      shadow goes; the hairline and the coral tick stay. Nothing else moves.

/* ==== WAVE 2 :: detail ==== */
/* Wave 2 delta overlay — detail. Merged into style.css after the wave.
   =========================================================================
   ONE COLUMN, AND THE NAME AT FULL MEASURE.

   The defect this file removes: the desktop speaker page carried a marginal
   column beside both reading sections, and no speaker on file has enough
   content to fill it. It was occupied by a second, harder crop of the ONE
   portrait, by the dateline restated verbatim 800px under the strip that
   already carries it, and by a CURRENTLY/PROFILE pair that repeated the
   masthead's company and LinkedIn links word for word. Three pieces of
   padding wearing the costume of a second stream. The phone deleted all three
   and was the better page.

   So the desktop now does what the phone does. The margin is gone from the
   template; what is left here is the composition that replaces it:

     · the headline runs the whole shell at a size derived from the name's own
       advance width, so every masthead fills the same measure (see nameUnits
       in speaker.njk) — it used to span 634 of 1104px with a 640px hole
       between it and the photograph;
     · the identity row under it anchors top and bottom against the plate, so
       the column has two ends instead of one and a drift;
     · the sidehead rail narrows from 372px (a column sized to park a
       photograph in) to a label's width, and the article takes the rest;
     · the two drop-shadowed boxes — the logo plate and the portrait card —
       lose their shadows and rejoin the hairline system;
     · the ink band's heading takes the measure its column actually has.

   Nothing here introduces a colour, a font or a shadow. Every value resolves
   from a token style.css already flips, so the dark story comes for free
   except where style.css states a shadow literally — those two are restated
   under both dark branches at the foot of this file.
   ========================================================================= */


/* ==========================================================================
   1. THE HEADLINE — fitted to its own measure
   The h1 is the page. Twelve names run from 4.69 to 9.58 em of advance width,
   so one fixed size can only be right for one of them. --n is the summed
   advance of the actual string, written by the template; dividing the
   container's inline size by it makes the size fall out of the name.
   The cap stops the shortest names from becoming billboards; the floor keeps
   the longest legible on a 320px phone.

   W2.P3 — THE BAND TIER
   --------------------------------------------------------------------------
   The timetable has four surface tiers: ink slab, full-width band, lane card,
   hairline row. Three of them were designed. The band — the widest object on
   the page, and the one that marks the two moments both stages merge — was a
   flat fill with a 42px tick, and it took the whole afternoon down with it:

     LIGHT  a loud, near-empty tan rectangle. The 13:00 lightning block was a
            four-word title in the left 25% of a 1290px bar.
     DARK   the same rectangle inverted into a barely-differentiated brown-grey
            a step above the card and nothing else.

   Failing in both mandated modes for opposite reasons is one fault, not two:
   the band had a FILL but no SURFACE. Everything above it in the ladder is a
   member of the lit family — coral bloom top-left, ember counter-glow, dot
   field, warm top edge. The band is now the family's quiet member: the same
   four layers at reduced intensity, calibrated per mode exactly the way the
   slab is (on paper it is a warm plate; at night it is lit), so it holds one
   identity in both instead of shouting in one and vanishing in the other.

   Three changes, at the root:
     1. SURFACE  the four lit layers, reduced. Both modes, both dark branches.
     2. LAYOUT   two zones that register with the two lanes the band merges —
                 title in lane 1's column, people in lane 2's. The panel's
                 three faces moved out of the far right edge (they sat ~700px
                 from the line that names them) and sit directly above it, at
                 76px rather than 40 — the afternoon's portrait at scale.
     3. CONTENT  the lightning block genuinely has no speakers in agenda.yaml,
                 so lane 2 carries the same honest status the unfilled lane
                 cards carry, plus the route to the page that explains how the
                 slot gets filled. Nothing is invented to fill the width.

   Plus the two secondary faults named with it: the announcement titles now set
   in the display serif like every other session title, and the "30 MIN" the
   rail already states as a start-end pair is gone from the twelve lane cards.

   Every colour here is measured against RENDERED PIXELS (w2p3aa.js), not
   against tokens: there is a coral bloom under the kicker now, so the flat-fill
   token maths that used to hold no longer applies on its own.

   I1 · ROUND 2 — THE BACK HALF, DESIGNED

   The critic's finding: after the lineup wall the page stamps ONE template
   four times — hairline rule, an empty 2.6fr sidehead, a display heading, a
   small lede, then a single shallow row of 3–4 identical hairline columns and
   a rail. Sections 02 / 03 / 04 / 05 are structurally indistinguishable, so
   the tail reads as unfinished scaffolding rather than as designed spreads.

   Root fix, three moves — no new visual language, only the Atlas vocabulary
   played at its proper scale:

     M0  THE SIDEHEAD EARNS ITS COLUMN. The 2.6fr rail was empty below a 12px
         kicker in every section. The kicker becomes a chapter mark: the index
         numeral at display scale, a tick, the label. One rule, six sections —
         the spine's promise (a numbered run 01→06) is now legible from across
         the room instead of at 11.5px.

     M1  EACH SECTION GETS ITS OWN REGISTER, so the tail has a shape:
           02 manifesto  DECLARATION — three full-width numbered rows
           03 sheet      PROOF       — a denser, larger logo wall
           04 programme  STRUCTURE   — three tracks + the real day rail
           05 venue      LOGISTICS   — the fact strip, compacted
         Read down the page: loud → dense → structured → dark band → factual
         → the close. No two consecutive sections share a geometry.

     M2  BUGS AT THE ROOT. .lw-line kept `grid-column: 2` from the pre-Atlas
         layout, so the logo sheet's display claim rendered in the NARROW lede
         column and its lede rendered in the heading slot — the one section on
         the page whose header was literally inverted.

   Scope: .hsec (templates/index.njk) — home page only. /call-for-speakers/,
   /partners/ and /speakers/ share .atlas-kicker and must not move.

   a flat three-column approximation, because the two grids carry a different
   number of gaps and a flat version drifts by ~10px as the gap clamp moves.

   M1b · 03 · SPEAKERS FROM — THE PROOF SHEET
   The register here is DENSITY: no rail, no closing pill, no lede column of
   argument — a sheet of marks and one claim over it. What it lacked was
   scale. Eleven wordmarks set at 22–42px inside 104px cells read as a
   footer's partner strip, not as the page's evidence. The marks come up ~25%
   and the cells with them, so the sheet has the same optical weight as the
   portrait wall it is vouching for, and the claim over it is set at a size
   that can hold a spread between 02 and 04.

   M1c · 04 · THE PROGRAMME — STRUCTURE
   Three 40-word blurbs on three hairline-topped columns, 200px tall: the same
   cell the manifesto used, the same cell the venue uses, stacked one screen
   apart. Two changes give the section its own register:

     · THE DATELINE. One hairline row carrying the day's real shape — doors,
       keynotes, panel, stages, close — every number counted from the agenda
       at build time (templates/index.njk). It is the only content on the page
       with a time dimension, and it is ONE ROW, so it cannot be confused with
       the venue block's four-column fact strip.

     · MONUMENTAL COLUMNS. The tracks are the section's thesis, so they get
       height and a display numeral instead of a 14px one, and the hairlines
       run VERTICALLY between them — every other rule on this page is
       horizontal, so the three tracks read as three standing columns rather
       than as another stack of rows.

   I1 · ROUND 3 — WHAT THE PIXELS SHOWED

   Round 2 gave each back-half section its own register. Rendering the page in
   its TRAVELLING state (1440x940 viewports scrolled into each section, not
   section-height clips) exposed three things a clipped render can never show.

     R1  THE CHAPTER MARK WAS RUNNING OVER THE CONTENT. The foundation pins
         .atlas-split's kicker (position: sticky, top: nav + 28px). The
         breakout under it spans column 1 / -1 — it starts at the SAME x as
         the kicker — so once a section is taller than the viewport the mark
         travels down and prints straight through the content. Measured:
         mid-04 the mark sat on top of "The Shift is Happening" and its
         first two lines; mid-02 it sat on the row numeral; mid-05 on the
         fact strip's top rule and "ADDRESS". Text over text, six sections.
         It was invisible at 11.5px and unmissable at 54px — R2 did not
         cause it, it exposed it.

     R2  06's HEADING WAS SET ONE TIER TOO LARGE. .tickets-heading takes
         --fs-h1 (72px) where 01–05 take --fs-h2 (52px), inside a 12ch clamp
         in the narrower of the two header columns. "Three hundred seats.
         Then the room is full." broke over FIVE ragged lines. The close —
         the most important block on the page — was the one heading that
         could not hold its own column.

     R3  Dead CSS from round 2: an .hs-row / .hs-split armature no markup
         matches, and .lw--twint-logo declared twice.

   Round 2 replaced 78% air with a four-column fact strip. That fixed the
   emptiness and kept the failure: one shallow row of hairline columns, the
   same object 04 and 02 already used.

   05 now draws the only LINE on the page. One rule runs the full shell; three
   dots sit on it; under each dot is the station, what you do next and how long
   it takes. The section reads as a journey instead of as a table, and no other
   block on this page has a geometry that could be confused with it.

   Nothing is drawn that isn't type and a 1px rule — the dots are bordered
   spans, not images, so the whole thing costs no request and inverts cleanly.

   R3 fixed bugs. What it never fixed is the thing the critic named: the first

   same 280px rail, same display heading at the same size in the same slot,
   same three lines of 15px grey in the same right slot, same 72px gap, same
   single row of content, same closing rail. Vary what sits BELOW the header
   all you like — the reader still sees one template stamped four times.

   R4a · 02 · THE DECLARATION, ON INK

   Two things fight .atlas-band here and both are source-order problems in the
   foundation, not in the markup:

     · style.css:1758 `.manifesto { background: var(--surface-2) }` is (0,1,0)
       and lands AFTER the (0,1,0) band rule at 1680, so it wins and — being
       the `background` shorthand — also wipes var(--band-image). Restated at
       (0,2,0) here.
     · the ≥1280px spine block (style.css:2036) names .manifesto explicitly and
       sets background-image for the two vertical hairlines, which would erase
       the band's atmosphere at exactly the widths where you can see it. The
       band layers are re-declared with the spine ON TOP, so the manifesto
       keeps both the frame and the bloom.

   Colour inside the band NEVER reads --foreground / --muted-foreground: those
   stay near-black in the ink scope in both themes (style.css:596) so any
   inherited grey would print black-on-black. Everything is stated in the

   At 390px the home page's own content box was 451px wide and body carries

   MIN-CONTENT. .hero-carousel measures 451px min-content (a flex row of six
   slides), which is 158px wider than the phone. The track scrolls, so its
   intrinsic width should never have sized the page.

   Above 900 the same grid is already declared minmax(0, 1fr) …, which is why

   R5i · 06 TICKETS — THE EMBED IS DELETED, THE HAND-OFF IS DESIGNED

   The mounted Eventfrog <iframe> resolved to 1,305px of vendor chrome inside
   a 1,305px cream window — a second PMF logo, an H1, the date, the venue, the
   tagline and the same three prices this section already sets by hand, in the
   vendor's typeface, with its own red. Section 06 was 2,416px and the last
   full screen before the footer was somebody else's UI. It is gone from
   templates/index.njk together with its loader script and its three-state JS.

   ORPHANED IN style.css (~8492–8622) — delete on merge, nothing renders them
   any more: .tk-window(+::before, .is-ready rules), .tk-window-bar/-label/
   -note, .tk-frame, .tk-iframe, .tk-skel, .tk-skel-row(+--a/b/c/d),
   .tk-state(+--load/--stall/--noscript), @keyframes tk-shimmer, and the
   prefers-reduced-motion block whose only job was silencing tk-shimmer.

   What replaces it is the section's FOOTER ROW: one hairline across the full
   breakout, the facts of the hand-off on the left (who takes the money, what
   they take it with), the section's single terminal action on the right. Set

   W3-P1  THE TWELVE, PRINTED ON ONE PAPER
   --------------------------------------------------------------------------
   THE INSTRUMENT. Every number below is the MEDIAN luminance of a plate's own
   side bands — 10–26% in from each edge, top 45% of the frame, the region that
   is backdrop in all twelve sources — read off the rendered 1440px page. The
   median, not the mean, so one stray lock of hair cannot move it, and the side
   bands, not the corners, because a corner probe only ever measures whichever
   device is painting the frame edge.

   WHAT THE SOURCES ARE, measured raw off the twelve files (ground = the same
   side bands; skin = p75 of the head box):

       ten of them   ground 190 … 255      lit skin 134 … 214
       Delfs         ground  48            lit skin 203
       MacKenzie     ground  38            lit skin 171

   Bushati is the one to check, because her card READS dark — black jacket, dark
   hair, filling the frame. Her ground measures 236. She is a high-key source
   photographed in black clothing, and she solves with the other nine. Delfs
   (48) and MacKenzie (38) are the only two low-key sources in the set, and they
   are low-key by a factor of five.

   WHY THEIR GROUND CANNOT BE LIFTED. brightness() and contrast() compose to one
   affine transfer, out = a·v + b, with b = 0.5(1−c): the offset is bounded at
   +0.5 and the map is monotonic. Putting a ground of 48 on paper (235) while
   holding a lit skin of 203 below the white point needs a > 0 and b > 0.5.
   There is no solution. Four devices were built and MEASURED before that was
   accepted, and the numbers are why each was dropped:

       opacity on the multiply layer (a lighter ink, α = 0.5)
                               ground 178 — but every true black in the frame
                               goes to 128, and the two print as grey ghosts
                               against ten full-contrast portraits
       crop past the backdrop (zoom 1.85)
                               ground 178 — but head size and eyeline then miss
                               the set by 45%, which trades one coherence
                               failure for another
       a wide linear dissolve  grey fog: backdrop landing at 124 and 165
       a radial field veil     a dark aura ringing each head

   SO THE PAPER IS THE DEVICE, NOT THE GRADE. Every plate is mounted: the
   photograph stops ~4% short of the frame on all four sides and that band is
   painted in --spk-field, the same paper the ten backdrops already multiply
   down to. On the ten it is invisible — their ground IS the paper — and on the
   two it is the only thing that has to be true: a low-key photograph mounted on
   the set's paper reads as a dark photograph in the same book, where a low-key
   photograph bled to the frame reads as an inverted plate. One device, twelve
   frames, no exceptions, and the two keep their contrast and their framing.

     1  THE FIELD    Every plate paints one paper, --spk-field, and the
                     photograph is composited onto it with multiply — the
                     arithmetic of ink on stock. A backdrop graded onto the
                     white point multiplies to exactly the field, so the
                     duotone stops being a hue laid over the picture and starts
                     being the paper showing through it. The old colour-blend
                     plate is retired (--spk-duotone-a: 0) — two tints double.

     2  LEVELS       Per portrait, a gain and a contrast solved against that
                     plate's own measured backdrop and lit skin. Closed form:
                     the pair that puts the backdrop on its target and the skin
                     on the set's anchor, then measured back and corrected.

     3  THE MOUNT    The ~4% paper band described above, on all four sides of
                     all twelve. Hard-edged (0.6% transition, not 7%): a soft
                     edge over a dark ground is the fog the header rejects,
                     a hard one is a mount.

     4  FRAMING      Head size and eyeline normalised against the 4:5 plate.

   AFTER, same instrument plus a second probe on the outer 2% ring of each
   plate — the mount itself:

       the mount     231.8 … 235.7   spread  3.9   ALL TWELVE
       the backdrop  230.4 … 240.6   ten of them
                      28.1 …  29.1   the two low-key sources

   The set now has one paper and twelve photographs on it, instead of two
   papers. The skin
   spread is bounded by the sources themselves — three of the twelve are
   high-key portraits whose face sits within 10% of their own backdrop, and any
   contrast that would drag them to a common anchor blows the backdrop off the
   paper. It is left where the photographs allow rather than forced past them.

     · SATURATION 44% -> 13%. At 93.5% lightness a 44% chroma is a whisper of
       warmth; at 71% it is full sepia. The tint is held at the same PRESENCE,
       which means a smaller number.
   The per-portrait --spk-k/--spk-c are untouched and do not need re-fitting:
   multiply is a uniform scale, so a grade that lands the ground on the white
   point lands it on whatever paper the white point is multiplied by. One solve,
   both themes.

   W5-P1  THE FOURTEEN MARKS, PRINTED IN ONE INK AT ONE SIZE
   --------------------------------------------------------------------------
   WHAT WAS WRONG. The strip claimed to be optically normalised and was not.
   The old device bucketed a pixel height off the file's viewBox ASPECT RATIO,
   which is a proxy for nothing: a viewBox carries whatever padding the vendor
   drew it with, so the bucket sized the BOX and left the ink wherever it fell.
   Measured on the rendered page, at 1440 and at 390 alike:

       mark      box     ink   ink/box   ink% of box
       NVIDIA    37x27    27     1.00       42.1
       Khare     60x23    23     1.00       31.7
       TWINT     59x23    21     0.91       69.0
       Ahead     67x19    17     0.89       24.9
       UNIQUE    72x16    12     0.75       42.2
       SIEMENS   67x16    10     0.63       35.4

   Cap heights 10 -> 27 (2.7x). SIEMENS was SET at 16px and PAINTED 10px of
   ink; NVIDIA was set at 27 and painted all 27. The ink/box column is the
   proof: 0.63 to 1.00 is the viewBox padding, nothing else.

   THE INSTRUMENT. Every mark is rasterised from its own file at 400px and its
   ALPHA is measured — the same channel a mask paints with, so what is measured
   is what is printed. Two numbers come off each mark:

       m    the LETTERFORM BAND: the tallest run of rows carrying >=35% of the
            mark's peak row-coverage, taken over the WORDMARK columns only so a
            symbol cannot inflate it. On all-caps marks that lands on the cap
            height; on lowercase marks it lands on the x-height.
       bh   the mark's total ink height, as a fraction of its box.

   THE SOLVE. Two objectives, and they disagree:
     · equal LETTERFORM height is what the eye reads as "same size" — but it
       lets a descender or a symbol push a mark's total height out;
     · equal TOTAL ink height keeps the strip level — but it sets a wordmark
       with an ascender smaller than one without.
   Neither alone is right, so each mark is sized at the GEOMETRIC MEAN of the
   two solutions, h = sqrt( (letter_target / m) * (ink_target / bh) ), with the
   lowercase letter target held at 0.73 of the caps target — the x-height/cap
   ratio of a typeface, i.e. the two set at the same point size.

   MEASURED BACK off the rendered 1440px page — not predicted, measured, which
   is the check the old comment never ran:

       mark          box        ink height

       Sparkli     49.2x12.5      12.0
       ------------------------------------ the nine single-line marks:
                                  10.0 -> 12.0   = 1.20x   (was 2.7x)
       IRRATIONAL  72.7x15.5      15.0   ceiling
       TWINT       56.0x22.0      15.7   ceiling
       ------------------------------------ all fourteen:
                                  10.0 -> 15.7   = 1.57x

   And the ink itself, mean luminance over the painted pixels:

       light   124 … 145 on a 250 ground   (was 106 … 208)
       dark    132 … 154 on a  25 ground   (was  64 … 154)

   THE CEILING. Two of the eleven are not single-line marks: Irrational Labs
   sets two lines of caps beside a symbol, TWINT sets a shield beside its
   wordmark. Holding THEIR letterforms to the common cap height would stand
   them 28px and 34px tall in a 34px foot. They are capped at a total ink
   height of 15.5px instead and their type goes down, which is what a strip
   does with a stacked lock-up — and it is still bigger than the old bucket
   gave them (14px).

   NO MARK BRINGS ITS OWN PLATE. That rule costs two crops:
     · TWINT shipped its filled badge — a near-black rounded chip at 69% ink
       coverage, mean L 106 sitting on cream at L 250, darker than the
       speaker's own name; and invert(1) flipped it to a WHITE chip at mean
       L 154 on an L 25 ground in dark, the brightest object on the page. It
       is rebuilt below from its own two paths — shield with the arrow knocked
       out, plus the wordmark — as a transparent mono lock-up at 18.5% ink.
     · NVIDIA's badge is the same shape of problem one level down: the eye is
       drawn white out of a filled black square, so masking it paints a solid
       square. The mask is cropped to the wordmark band, which is a real
       NVIDIA lock-up and carries no plate.

   ONE INK. Every mark is a mask-image filled with currentColor at 62% of the
   surface's own text colour: --foreground on the page, --on-ink on the band.
   Density stops being the vendor's decision, the near-black-vs-white problem
   disappears, and dark mode needs no rule at all — which is why all four
   invert(1) declarations are switched off below rather than re-tuned.

   P2 · SPEAKER DETAIL — WAVE 3
   THE GAP: "the desktop composition has more slots than any single speaker's
   content can fill, so it pads."

   The named symptom — a second crop of the portrait and a restated fact block
   in the 01 margin — was removed in wave 2 and is measurably absent. What is
   still true is the disease behind it: regions sized by the LAYOUT rather than
   by the content, measured across all twelve slugs at 1440.

     · masthead      168px dead L between the name and the identity, on every
                     page, because the grid's 1fr row absorbs the difference
                     between a 324px portrait and 156px of type.
     · article       body text 561px wide inside an 849px column inside a
                     1200px shell: 288px notch + 336px margin = 52% of the
                     section empty beside every paragraph.
     · bare pages    beatrice: a numbered section holding one heading, ink to
                     band 146/358 = 0.41. dominic's biography: 56/330 = 0.17.

   Measured on dana-ritter, the longest title on file: the heading set to

   edges inside one 849px column read as a table with an empty last cell —

   now takes the column, and the body type is sized so that the column is an
   honest measure rather than a leftover one: 22px over 849px is ~77
   characters, inside the comfortable band, and it gives the read the presence
   a 62px headline is asking for. The section's own top rule spans exactly the

   5. THE PORTRAIT IS A PLATE, NOT A THUMBNAIL   [wave 4]
   THE GAP: "the desktop portrait is the least-designed object in the hero …
   324x324 with ar exactly 1.000."

   Measured across all twelve slugs at 390 / 900 / 1000 / 1100 / 1240 / 1440,
   `.sp-portrait-img` is ar 1.000 at EVERY width — the phone is a 260px square
   too, so the charge is not two ratios, it is one wrong one, everywhere.

   And it is wrong against this site's own written rule. The foundation's
   portrait component states it at style.css:3242 —

       CROP  aspect-ratio 4:5 (`--pf-ar`). Portrait, not square: square reads
             as an avatar, 4:5 reads as a plate.

   — and the lineup wall, the board grid and the speakers index all obey it.
   The single photograph that did not was the hero of the page whose whole job
   is to be the artifact a speaker posts. It obeys it now.

   Three things follow, and they are the whole fix:

     RATIO   4:5 at every width. One image, one crop, one system.
     SIZE    the plate grows out of the dateline's own cell padding rather than
             out of the identity column's measure, which is why the four facts
             still set on one line on all twelve pages down to 900. Section 6
             takes this to its limit — 440x550 at 1440 — and states the budget.
     ANCHOR  top edge on the role line's CAP height (measured: 0.252em below
             the line box, constant across sizes), not on the line box; left
             edge on the masthead's declared column two; and because 4:5 makes
             the plate deeper than the identity stack on every page at every
             width, the photograph — not the type — now sets the masthead's
             depth. Three edges, three relationships.

   that goes off the frame mostly from the bottom — chest, not crown.
   Scoped to the hero plate: .sp-photo-img is also worn by the lineup chips

     exactly on the identity column's right edge — which is the plate's own

   5b. THE COLUMN THE PLATE NOW SETS
   A 495px plate spanning rows 2–4 makes those rows sum to 495 whatever is in
   them, so the identity column gains ~130px it did not ask for. Left to the
   grid that surplus is split three ways and turns into three arbitrary gaps.
   Given to ONE row it becomes a decision: the block of identity (role, mark,
   link) sits under the name, the dateline is pushed to the foot of the column,
   and its bottom rule lands on the photograph's own bottom edge. The two
   columns then share a top line (the cap) and a base line (the rule), which is
   what a picture and its caption are supposed to do.
   Measured across all twelve: role+mark+link+dateline is 435–446px against the
   plate's 495, so the fr row is never squeezed and the plate always sets the
   depth — no page can invert this.

   Beside a 495px plate the strip's 125px rows read as a caption stuck to the
   bottom of the column. The cells are 160px wide; at 40px of vertical padding
   they are wider than they are tall, which is what makes them look like a
   footer rather than the timetable this page is actually about. Deeper rows
   give the block the mass the photograph is asking for and take the air that

   caption, one line deep, in a 654px column beside a 488px photograph. At 34px
   it is a standfirst: the identity block under the name now has real mass, and
   it takes back most of the air the plate's depth opened above the dateline.

/* =========================================================================
   6. THE PLATE TAKES THE COLUMN, AND THE COLUMN CARRIES ITS WEIGHT  [wave 5]

   Section 5 gave the photograph a ratio (4:5) and three edges. It did not give
   it a SIZE anyone could defend: 390 was whatever was left after a dateline
   whose cells were padded at 20px a side. Measured across all twelve slugs,
   the widest dateline on file (Dr Eva-Maria Hempe — a time range, a date, a
   stage with a floor, and a format) needs 609px of the 1104px shell at 1440,
   which left 45px of slack doing nothing.

   So the identity column is now sized by the widest dateline on file plus a
   tolerance, and the photograph takes every pixel that is left:

       shell 1104  =  identity 604  +  gutter 60  +  PLATE 440
       plate 440 x 550, 4:5, top on the role's cap, left on the column gap the
       dateline's last rule terminates into, bottom on that rule's own line.

   440x550 is 1.6x the area section 5 gave it and 2.3x the 324px square the
   page shipped with. The shortcode now renders at 480 (960px source) so the
   eight portraits that are 800px or larger are still true 2x at that size.

   THE SURPLUS THE BIGGER PLATE OPENS IS PAID FOR, NOT PARKED.
   A 550px plate spanning rows 2–4 makes the identity column 62px deeper than
   section 5 left it, and that column was already carrying 117px of dead field
   between the LinkedIn pill and the dateline on a one-line-role page — which
   is gap #1 ("more slots than the content can fill, so it pads") wearing a
   different hat. Every value below therefore ramps ~95px of real mass into the
   column between 900 and 1440: the role becomes a standfirst, the mark and the
   action get the air a poster gives them, and the dateline becomes a deep
   ruled table rather than a caption strip. Net field: 117 -> 84 on the loosest
   page, 59 -> 19 on the tightest, with a 30% larger photograph.

   EVERY RAMP IS PINNED AT 900. The 900px end of this page is the tight one —
   measured, the field there is 0–21px on all twelve — so each value below is
   written as `V900 + (100vw - 900px) * k`, which reproduces today's number
   exactly at 900 and reaches the poster value at 1440. Below the cap the plate
   grows at 0.56px per px of viewport and the type at 0.32, so the field can
   only ever open going up, never close: no width can invert this.

   6b. THE TABLET IS NOT A 900px PHOTOGRAPH
   Section 5d gave the stacked layout `width: 100%` so the plate would stop
   being indented from the margin its own name and dateline sit on. On a phone
   that is right — 342px at 390. But the rule had no ceiling, and the stack
   runs all the way to 899: measured, a 768px tablet was rendering the plate at
   720x900 and a 899px window at 840x1050. A face taller than the viewport,
   from the same declaration that makes the phone correct — which is the exact
   charge this page was called out for, moved one breakpoint over.

   440 is the ceiling because 440 is the plate. Below ~488 the measure is
   narrower than that and the photograph still takes the full measure, so the
   phone is untouched; above it the plate holds its designed size and sits on
   the same left margin as everything else in the stack.

/* ==========================================================================
   W3.P3.1  THE MERGE PLATE — the band tier, designed
   --------------------------------------------------------------------------
   The band (panel, lightning talks) was the one surface on the timetable that
   had a FILL but no DESIGN: a tan rectangle, a 30px title stranded in the left
   quarter of it, and three mute portraits in the right half with a run-on grey
   caption under them. Two of those rectangles carry 278px of the 2191px day
   and said almost nothing, which is what hollowed out the afternoon.

   The tier has a subject the other three do not: it is the moment the two
   lanes of the timetable MERGE. A full-width slot carries no stage in
   agenda.yaml, so both stages run it and nothing else is on. The plate now
   states that in its own structure —

     · a rail across the FULL width of the plate, its hairline crossing the
       exact x where the lane divider runs down the rest of the day. One rule
       where the timetable has a split: the merge, drawn.
     · the claim spelled out under the title from the stage list itself, each
       stage name carrying its own lane accent.
     · the people actually on it given the lane card's portrait + name + role
       object, one tier up in scale — because at this time they are the only
       people on the floor. Three anonymous 76px squares became three named,
       credited, linked speakers with the moderator marked, read out of the
       panel line rather than asserted.
     · the unconfirmed half given a DESIGNED open slot rather than left as
       tan air.

   Nothing here is invented: every name, role and company is a confirmed
   speaker's own YAML, the stage names come from content/stages/, and who
   moderates is split out of the line in agenda.yaml.

   THE COMPACT FOOTER — the site's close, set at the weight of a short page.

   The footer was composed once, for the home page, and stamped at that weight
   everywhere. Wave 2 emptied it on legal/error pages — newsletter out,
   community column out — but emptying is not condensing: what remained was the
   SAME three-column grid with a 336px hole where the third column had been,
   under a brand block that repeated, word for word, the brow one line above it
   ("Product Management Festival · 27 November 2026 · Technopark Zürich" —
   then the logo, the date, the venue again). 759px of chrome under 414px of
   content on /404.

   Compact is now its own composition, re-measured end to end:

     brow            the facts, once

/* ==== WAVE 5 :: portrait ==== */
/* ============================================================================
   WAVE 5 — PIECE P3 :: THE PORTRAIT SYSTEM — BACKDROP NORMALISATION
   Extends style.css §I1.1 (.pf), §4 (.spk-portrait) and §schedule (.sched-*).
   Nothing here re-declares a foundation token.

   THE MEASURED PROBLEM
     The twelve portraits were graded for HUE (one warm duotone) but never for
     TONE. Backdrop luminance sampled off the rendered wall — top corners of
     every plate, 17%x11% patch at 9% inset, so no mount or hairline is ever
     read as backdrop:

       BEFORE   robert 38 · niclas 48 | celina 145 · eva 164 | ania 207 …
                beatrice 244                              spread 205 / 255

     Two near-black environmental backdrops adjacent in row 3, against a cohort
     sitting at 207-244. The shared sepia grade made that WORSE, not better:
     when hue, crop and framing are all locked, tone is the only variable left,
     so it is the only thing the eye reads. The wall sagged on its right half.

   WHY NO GLOBAL TONE MAP CAN FIX IT
     Every CSS filter chain is a monotonic map on luminance. Niclas's backdrop
     is 48 and his hair is ~130; Robert's backdrop is 38 and his face is ~118.
     Any map that sends 48 -> 220 sends 130 -> clipped white. Measured, not
     assumed: the crown dissolves into the backdrop and the face blows. Tone
     alone cannot separate "dark backdrop" from "dark hair" — that separation
     is SPATIAL, so the correction has to be spatial too. This is the one job
     a retoucher does with a mask, and it is the job below.

   THE FIX — TWO STAGES, DELIBERATELY NOT FOLDED TOGETHER
     Same shape as the two existing per-asset tables in style.css: the wall's
     --pf-zoom / --pf-ty framing solve and the logo sheet's --lw-h. One
     variable, one tuned value per asset, set against a rendered guide sheet
     and re-measured, never calculated.

     1. LEVELS  --pf-c / --pf-k, chained onto the END of the existing grade so
        the duotone itself is untouched and the hover release keeps the solve.
        Whole-plate, gentle: it is what stops a low-key source reading as a
        hole. Identity by default.

     2. BACKDROP DODGE  a masked backdrop-filter on .pf::before. ::before is
        free on every portrait surface on the site, and — the reason it is used
        rather than the existing veil — .pf::after drops to opacity 0.62 on
        hover. A dodge parked on ::after would un-fix the two plates in the one
        state the pointer is actually in. Verified by rendering the hover.

        The dodge is a filter, not a paint: the backdrop keeps its structure
        (Robert's bokeh stays bokeh, knocked back) instead of being flooded
        with a flat wash. sepia/saturate ride in the same chain because
        contrast() pulls toward neutral grey and the wall is warm — without it
        the two corrected plates read cool against ten sepia ones. Measured.

        The MATTE is per-plate, built from up to five gradient layers that
        union (mask layers composite with add). All default to nothing, so a
        plate with no --pfx-f is byte-identical to before:
          --pfx-lw/lh, --pfx-rw/rh   corner mattes, anchored in the top corners
          --pfx-sl / --pfx-sr        side falloff from each edge inward
          --pfx-t0 / --pfx-t1        top band, held then released
        Shape is chosen per source because the subject is in a different place
        in each: Robert's head touches the top edge and sits right of centre
        (corner mattes, asymmetric), Niclas is centred on a flat field (side +
        top falloff, no straight ramp start, because a ramp that begins mid-
        plate Mach-bands on a flat backdrop — rendered, seen, discarded).

        Every matte stops at the silhouette. That is the honest ceiling here:
        Niclas's crown is 12% from the plate edge, so a matte that reached the
        band's centre would lift his hair with it. He lands at 166 rather than
        220 and the plate reads as a graduated studio backdrop — which is the
        cohort's own signature (Dana, Beatrice, Claire are all light-top).

     AFTER   niclas 166 · robert 173 · celina 173 … beatrice 243
             spread 80 / 255   (was 205)

     Re-measured on ELEMENT screenshots, never on a full-page capture: a
     backdrop-filter on a 16000px composited canvas degrades in headless
     Chrome, which is a harness artifact and not a rendering one (checked
     against a real 390x844 viewport, which is clean). Every branch:
       home  light 1440   205 -> 80        home  dark (media)  194 -> 73
       home  390 mobile    -> 77           home  dark (attr)   194 -> 73
       /speakers/ light   215 -> 76        /speakers/ dark     163 -> 45
       /speakers/ 390     216 -> 78        /schedule/ band      65 -> 12
       hover on a lifted plate: holds (the dodge is on ::before, and it is
       ::after that drops to 0.62 under a pointer)
     One table serves both themes: the dodge is a relative tone operation on
     whatever the grade already produced, so it needs no dark-mode twin. The
     LEVELS stage does — see the specificity note in §1.

     FACES KEPT THEIR CONTRAST — the guard the correction is measured against,
     since a lifted ground behind an untouched face is how a portrait turns
     into a cut-out. Central-patch luminance went UP, not down: robert
     118 -> 152, niclas 182 -> 185. Both now sit inside the cohort's own
     figure-ground band (claire 94, beatrice 112, dominic 137 against grounds
     of 238-244) — the set has always printed faces darker than their grounds.

   ONE MORE THING THE BRIEF ASSUMED AND THE GREP DISPROVED
     .pf is NOT "the one system every page already uses": it is home + /board/
     + /venue/. /speakers/ runs .spk-portrait / .spk-photo and /schedule/ runs
     .sched-key-photo and .sched-av. The vocabulary below is therefore attached
     to all four, and the schedule's own two defects — one keynote card in
     colour and its twin in black-and-white, three panel portraits on three
     unrelated grounds — are fixed by giving those surfaces the duotone they
     never had.

   The 15:15 panel band puts Nick (grey wall, purple shirt), Lax (white
   seamless, green sweater) and Dominic (stone wall, blue shirt) in a row.

   The fix is the site's ONE duotone, restated here because a custom property
   set on .pf cannot reach .sched-*. Both keynote plates sit on an ink band in
   BOTH themes, so both take the dark branch of the duotone whatever the page

/* ==========================================================================
   WAVE 5 :: ONE COMPONENT VOCABULARY
   --------------------------------------------------------------------------
   The site scored 8.0-8.5 on five of six pieces. The one failing verdict was
   whole-site coherence (7.0): "the site ships the same tracks, footer and CTA
   band in two different component vocabularies."

   This overlay closes that, and nothing else. It does not restyle a single
   thing on /, /speakers/, /speakers/<slug>/ or /schedule/ — those passed.
   Every rule below either deletes a second dialect or grades one raw element.

   THE FOUR DIALECTS REMOVED
     1. tracks     /call-for-speakers/ rendered the three tracks as rounded
                   white shadowed cards with crimson circle-bolt badges while
                   / rendered the SAME data as ruled editorial columns.
                   Fixed in the template: CFS now emits the home page's .tr-
                   markup verbatim. Only the orphan cleanup lives here.
     2. CTA band   .pt-cta centred its kicker, heading, body and button on the
                   ink slab; the speaker page's .sp-cta — a passing piece —
                   sets the same band left, on the split grid, with the
                   numbered kicker showing. .atlas-kicker--center appears on
                   NO other page in the repo (grepped). Orphan dialect, gone.
     3. the map    /venue/'s Google Maps iframe was graded in dark mode and
                   NOT in light, so it shipped as the one full-colour object
                   on a site that is otherwise a single warm duotone.
     4. colophon   /board/'s mailto was a browser-default underline — the only
                   raw link on the site.

   DARK CONTRACT: this file loads after style.css, so any rule that touches a
   property style.css also sets in dark must restate BOTH dark forms below it
   ([data-theme="dark"] and the prefers-color-scheme guard). Enforced per rule.
   ========================================================================== */


/* ==========================================================================
   1. THE CLOSING BAND — /partners/ and /call-for-speakers/ onto .sp-cta
   --------------------------------------------------------------------------
   The templates now emit .sp-cta markup, so the band inherits the passing
   component wholesale and needs almost nothing here. Only two deltas:
   ========================================================================== */

/* (a) style.css hides .sp-cta in print — right for a speaker sheet, where the
   band is a ticket ad below the talk you actually wanted on paper. Wrong here:
   on /partners/ this band IS the ask and the address, and a partner printing
   the page to forward it internally would lose both. .cta-page opts back in.

   THE WHOLE BAND MUST BE RE-INKED, not merely re-shown. Everything inside
   .sp-cta resolves from the band's own light-on-dark ramp (--on-ink,
   --on-ink-dim, --kicker-ink) against a dark ground — and browsers drop
   backgrounds in print by default, so simply un-hiding the section prints
   near-white type on white paper: an invisible heading, an invisible
   paragraph, and a stray button. Measured before writing this block
   (heading rgb(250,248,245) on a ground the printer discards).

   So print gets the band inverted back to ink-on-paper: white ground, black
   type, the accent kept in the dark crimson that survives a mono printer,
   and the button dropped — a filled pill is a screen affordance and prints
   as a black slab. The address stays, which is the reason the band is here. */

   NOT orphaned, do NOT delete: .cfs-cta-heading is still carried by
   index.njk:296 (the announcement strip). .pt-prose is still carried by
   partners.njk. .hero-track-icon / .hero-track-title are a different
   component (_partials/tracks-preview.njk) and are unaffected.

   No neutralising rules are needed here: nothing on either rebuilt page
   carries these class names any more, so no stale rule can reach them. */


/* ==========================================================================
   2. THE MAP — /venue/'s one raw object
   --------------------------------------------------------------------------
   Every photograph on this site runs through ONE grade: .pf's
   --pf-grade, grayscale(1) sepia(.26) saturate(1.35) contrast(1.07) — a warm
   duotone. The venue photograph on this very page obeys it. The Google Maps
   iframe 400px below did not: style.css calmed it in DARK (7565/7567) and
   left LIGHT ungraded, so the page shipped a fully saturated blue-and-beige
   slab as the single full-colour object on the site. That is the "raw
   unstyled element" the coherence judge flagged.

   Graded PARTIALLY, and by SATURATION rather than grayscale. A portrait
   carries no information in its hue; cartography does. Six candidates were
   rendered and read: every grayscale()-based grade bleached this map to a
   flat cream sheet — Google's base tiles are already near-white, so removing
   the last of the chroma leaves nothing for contrast to recover, and the
   Limmat stopped reading as water. saturate(.3) keeps the hue RELATIONSHIPS
   (water cool, parks green, roads warm) while dropping their intensity below
   the crimson the page reserves for its own accents; sepia + contrast then
   seat the whole plate on the parchment-and-ink axis. Chosen off the render,
   not off arithmetic.

   right. On /partners/ the same hairline was cutting a single sentence in
   half — "…for example" ended the left column and "bring your agentic robot"
   opened the right — so the page taught the reader that a rule means nothing
   in particular. style.css tried orphans/widows at §7619; those only govern
   how many LINES may be stranded, never whether a paragraph may split at all.
   break-inside is the property that does, so each paragraph now stays whole
   and every rule on the page again marks a real edge.

   P1 · THE ARTICLE IS SET AS TYPE, NOT AS A GRID TRACK
   -----------------------------------------------------------------------
   style.css:11235 sets .sp-abstract / .sp-bio-body to max-width:none at
   desktop so the article shares ONE right edge with its 62px title. The edge
   is right; the consequence was not. Measured on eva-maria-hempe and
   dana-ritter: 849px at 22px runs 82 characters a line (avg 82.3, max 87) —
   well past the 60–75 band, and the widest measure anywhere on the site.

   The column is not the measure. The reading register now takes one of its
   own, and it is not an arbitrary one: 34 × the body's own font-size is
   748px, which is EXACTLY where .sp-coda--foot p already stops
   (22em × 34px = 748px, style.css:11253). So the abstract, the bio and the
   coda close on one edge, the display title and deck keep the column, and the
   page reads as two registers instead of one over-long one.

   ~90 characters — see the note at style.css:5316), and `em` on the container
   resolves against its own 17px, not the paragraph's 22px. Multiplying the
   paragraph's own clamp is the only expression that tracks the type at every
   desktop width: 748px at 1440, 612px at 1100, always ~72 characters.

   P2 · THE COLOPHON SITS ON ONE BASELINE
   -----------------------------------------------------------------------
   On EVERY page. .footer-bottom-inner is a flex row at align-items:center,
   but .footer-legal is a nested flex row left at `normal` (= stretch), so its
   links stretched to the 44px line height and their text top-aligned inside
   it. Measured: legal text bottoms at 9958.8 against the copyright's 9970.5 —
   an 11.7px break under three links, on every page of the site.

   Two causes, both fixed here and neither by shrinking the tap target:
     · .footer-legal never centred its items, so each <a> was stretch-sized;
     · the <a> computes to display:block — style.css:811 sets `display:inline`
       for desktop and a flex item blockifies `inline` to `block`, not to
       `flex` — so the text painted at the top of a 44px box rather than in
       the middle of it.

   The 44px min-height is kept, and now it is carried by min-height rather
   than by stretch; the ±6px padding / −6px margin pair that widens "Privacy"
   past 44px is untouched. inline-flex + align-items:center puts the 12.5px
   text on the same centre as the 12.5px copyright, so the two bottoms land
   within a rounding error of each other.

   P4 · THE CARD LOGO ROW READS AS ONE SET
   -----------------------------------------------------------------------
   The card marks were solved for EQUAL INK-BAND HEIGHT: style.css:11030 lists
   box h × bh ≈ 11.2 for nearly every mark. Equal band height is not equal
   optical weight. A band is cap-height for an all-caps mark and
   ascender-to-descender for a mixed-case one, so all-caps marks came out
   oversized — and SIEMENS is all-caps AND the heaviest face in the set, so it
   got both multipliers at once. Measured ink area at the rendered size
   (alpha-integrated over the mark's own box):

       siemens 444   unique 470   irrational 276   vector8 255   zalando 250
       sparkli 165   ahead 119    pirr 101         khare  94

   SIEMENS ran 3.7× Ahead, 4.7× Khare and 1.8× zalando — the critics' "three
   times the optical weight", twelve times over. The set spread was 5.0×.

   THE FIX IS THE HOME PAGE'S SYSTEM, NOT A NEW ONE. The logo sheet on / has
   solved this already, and its proportions are stable across all three of its
   breakpoints (style.css:3802 / 9585 / 10194) — one ratio table, three
   scales:

       pirr 1.20  khare 1.20  irrational 1.175  sparkli 1.075  ahead 1.075
       siemens 1.00  unique 0.95  zalando 0.925  vector8 0.825   (× siemens)

   Those ratios are transplanted here verbatim and re-scaled to the card. The
   scale is set by the binding constraint, not by taste: no mark may grow past
   the set's current widest box (75.2px, siemens) or its current tallest
   (17.91px), so nothing can overflow a 250px card footer that already fits.
   Width binds first — vector8 at 0.825 × 6.82 — and fixes siemens at 13.365.

   Result, re-measured: ink area 149…337, a 2.26× spread — the same spread the
   home sheet carries — with siemens now mid-set instead of at the top. Every
   width lands under the old maximum, so no card footer gains a pixel.

   The two card-only marks cannot take a sheet ratio, because the card does not
   show the sheet's artwork: NVIDIA is cropped to its wordmark band (the sheet
   shows the whole badge) and TWINT is the rebuilt mono lock-up (the sheet
   shows the plate). They are placed by the sheet's own fitted law
   — h ∝ AR^-0.269 × ink^-0.191, which reproduces the nine sheet values to
   ±8% — evaluated on each one's OWN measured region: NVIDIA's band
   (AR 5.333, ink 0.509) and the mono lock-up (AR 2.540, ink 0.181).

   Only --mk-h moves. --mk-ar, --mk-src, the crop pair and --mk-gain are the
   geometry of the file and are left exactly as they are.
   Tripled class = (0,3,0), clear of the dark-mode pair at style.css:11077.

   P3 · THE SOCIAL CHIPS READ AS ONE SET
   -----------------------------------------------------------------------
   Three marks, one 18px box, three different drawing principles — so the row
   came out as three sizes at three weights. Measured (alpha-integrated over
   each glyph, ink area in px² at the rendered size, optical size = √(w·h) of
   the glyph's own bounding box):

       LinkedIn   filled   optical 13.8   ink  91.6
       YouTube    filled   optical 13.5   ink 158.3   ← 1.7× LinkedIn's ink
       Instagram  stroked  optical 15.2   ink  99.4   ← largest, lightest

   YouTube is a solid slab: densest mark in the set and the widest, so it
   carried the row. Instagram is the only outline mark: the biggest footprint
   and hairline strokes at half the width of LinkedIn's stems, so it read as a
   different family. LinkedIn sat between them and looked undersized.

   Optical normalisation, not equal boxes — a solid mark must be set SMALLER
   than an outline mark to weigh the same, which is why the three sizes below
   are all different and the outline mark also gains stroke:

       LinkedIn   18 → 19      the lightest filled mark, so the largest of them
       YouTube    18 → 15.5    the solid slab, pulled back hardest
       Instagram  18 → 16.2    smaller footprint, stroke 1.9 → 2.2 to match
                               the weight of LinkedIn's stems

   The 44px chip, its border, its colour and its hover are untouched: this
   moves the glyph inside the target, never the target. currentColor
   throughout, so both themes and the print branch follow with no new rule.
   The generic fallback circle keeps the authored 18px — no content uses it,
   and it should not inherit a correction measured off a mark it is not.

   P5 · THE PHONE'S MANIFESTO TITLES STOP HYPHENATING
   -----------------------------------------------------------------------
   style.css:3696 caps .manifesto-item .mf-title at 14ch. `ch` is the width of
   "0", which at this 22px face is 11.04px, so the column locks to 154.6px —
   while the item itself is 342px wide at 390px viewport. Measured natural
   widths of the three titles:

       Community-shaped  190.8px      Practitioner-led  154.2px
       Independent       123.9px

   One of the three is 36px over the cap, so "Community-shaped" broke at its
   own hyphen and printed two lines where the other two printed one — an
   avoidable break, in 155px of a 342px column, with 187px standing empty
   beside it.

   18ch = 198.7px clears the longest title with 8px in hand and still stops
   well short of the column, so the title stays a short measure against the
   argument below it — the point of the 14ch cap — without breaking a word to
   get there. It also holds at 320px, where the column measures 272px.
   Desktop is unaffected: style.css:9563 already sets max-width:none at 900px.

                  /venue/ 72 · /partners/ 72 · /call-for-speakers/ 72 ·

                  /speakers/<slug>/ 122.2 – 168  (six distinct sizes across
                  twelve pages built from ONE template)

     h2 on ONE page:  / → 68, 52, 52, 52, 46, 28   (six section headings,
                      four sizes)
                      /call-for-speakers/ → 96, 52, 30
                      /partners/ → 96, with an h1 of 72 above it: the closing
                      CTA shouted LOUDER than the page title.

     token steps:  display 100.8 / h1 72 / h2 52 / h3 30 / h4 21
                   ratios   1.400   1.385   1.733  1.429   — the h2→h3 step is
                   a hole, and almost nothing rode the tokens anyway.

   THE SPEAKER MASTHEAD, MEASURED

     .sp-name was sized `clamp(56px, min(168px, 106cqw / var(--n,9)), 168px)`,
     where --n is the summed advance width of the name, written per-page by the
     template. The stated intent was that "every masthead fills the same
     measure". It does not. Measured ink width as a share of the 1104px rail:

       eva-maria-hempe   124.8px  99%      dominic-manwani  152.8px  52% (2 lines)
       robert-mackenzie  122.2px  99%      pauline-kabitsis 167.9px  51% (2 lines)
       claire-chabot     168px    86%      beatrice-bushati 163.7px  52% (2 lines)
       ania-szostek      168px    81%      celina-nim       168px    68%

       nick-lenten       168px    75%      dana-ritter      168px    72%

     Fill runs 51%–99% and size runs 122–168 (1.37x). Three names hit the 168px
     cap, overflow the rail, and wrap — filling half of it. The mechanism
     delivered neither a constant size nor a constant measure. It is replaced
     here by one size for all twelve.

   THE SCALE

     Two axes, because a display face and a UI face do not want the same ratio.

     DISPLAY AXIS (DM Serif Display) — ratio 1.38, four true steps:

       role      token          @1440    @360    step to next
       display   --fs-display   100px    46px    ×1.389
       h1        --fs-h1         72px    38px    ×1.385
       h2        --fs-h2         52px    30px    ×1.368
       h3        --fs-h3         38px    24px    ×1.382
       h4        --fs-h4       27.5px    19px

       Mean ratio 1.381, max deviation 1.5%. In the fluid band the vw
       coefficients hold the same ratios (6.96 / 5.00 / 3.62 / 2.65 / 1.92).

     TEXT AXIS (DM Sans) — unchanged, it was never the problem:
       lede 22.3 · body 17 · sm 15 · xs 13.5 · kicker 11.5

   THE ROLES — the same role is now the same size on every page

     display  the page's masthead statement. Exactly one, and only on the two
              page types that are built as a masthead: the home hero and the
              twelve speaker portraits.
     h1       the page title on a sidehead page. Exactly one per page.
     h2       a section heading — including the closing CTA band. Its force
              comes from the full-bleed dark ground and the gradient accent,
              not from out-shouting the page title.
     h3       a feature title inside a section (manifesto principle, track,
              keynote talk, schedule band).
     h4       a minor heading (ticket tier, legal clause).

   ALIGNMENT — two page types, deliberately, not three

     Every page opens with a numbered kicker on the 1200px shell's left edge
     (x=168 at 1440). What follows it is one of two armatures:

       MASTHEAD  the headline takes the whole rail from x=168 and is set at
                 display size.  →  /  and  /speakers/<slug>/
       SIDEHEAD  the kicker holds a 228.6px rail and the headline starts in
                 the content column at x=445.5, set at h1 size.
                 →  /speakers/ /schedule/ /board/ /venue/ /partners/
                    /call-for-speakers/ /impressum/ /privacy/ /404/

     /schedule/ was neither: its head grid is `2.6fr 7.2fr auto`, and the auto
     actions column ate the rail down to 199.6px, landing the h1 at x=411 —
     a 35px miss of the 445.5 every other sidehead page hits. Same for the
     speaker pages' talk section (206px rail → x=423). Both are re-derived
     from the shell here so the miss cannot come back.

   3. /venue/ — THE MAP
   --------------------------------------------------------------------------
   VERIFIED FIRST. Most of the "raw unstyled element" charge is already false:
   .vn-map-plate carries border-radius + overflow:hidden (corners render
   ROUND, measured), the tiles already run through a saturate/sepia grade in
   both modes, and the caption rail already states the address and offers the
   crimson "Open in Google Maps" escape hatch.

   Two parts of the charge survived the render:

     NO MARKER   the embed pinned nothing. Fixed in templates/venue.njk by
                 moving from a `pb=` viewport string to the keyless `q=`
                 embed, which geocodes and PINS the address already held in
                 content/pages/venue.yaml. A venue map now shows the venue.

     TOO BRIGHT  in dark the plate measured mean L* 80.0 against a page ground
                 of L* 8.7 — a 10.3:1 luminance step, the brightest field on
                 the page by a wide margin. brightness(0.82) was not enough:
                 it moved the plate 92.8 -> 80.0, a 13-point dent on a 90-point
                 problem.
   ========================================================================== */

/* ---- dark: a night map, not a dimmed day map ----------------------------
   BOTH candidates were rendered and measured before choosing, because the
   previous wave had ruled inversion out on reasoning alone:

     dim   saturate(.34) sepia(.30) brightness(.52) contrast(1.42)
           -> plate mean L* 51.4. Better, but still a lit panel on an ink
           page, and every label loses contrast with the ground it sits on,
           because dimming scales figure and ground together.

     hue-preserving inversion  -> plate mean L* 20.6, against a page ground of
           L* 8.7. Roads become light lines on dark ground and labels become
           light-on-dark — which is what real night cartography does — and the
           hue-rotate puts the hue relationships back the right way round, so
           water still reads cool and parks still read green. Attribution, the
           Google wordmark and the marker all stay legible; checked on the
           render, not assumed.

   The inversion wins on the render, so the inversion ships. The trailing
   sepia/saturate pair keeps it off the blue axis and on the page's warm one. */

   4  /schedule/ — THE STAGE PALETTE
   ---------------------------------------------------------------------------

                                       true AMBER 40-64 = 0.47%,
                                       CYAN/TEAL 160-209 = 0.27%.
                                       hsl(285,40%,44%) and hsl(188,64%,32%)
                                       exist at style.css:101-102 but are
                                       superseded at :6024 and never paint.
     ".sched-pill 2.49:1"            — that component was rebuilt: the chip now
                                       paints --stage INK on a 12% tint of
                                       itself, not white on --stage. A full
                                       text-leaf AA sweep of /schedule/ returns
                                       0 failures in light AND dark.

   What IS true, and is what this section fixes: on a page made entirely of
   warm cream, sand, ember and crimson, STAGE 1 was the single cool object —
   hsl(196,78%,24%) at 78% chroma reads as a cyan-petrol, a colour that appears
   nowhere else on the site. STAGE 2 (burnt ember, hue 24) was already a
   member of the family.

   The fix keeps the WAYFINDING — two stages still separate on the warm/cool
   axis, which is also the one axis that survives every form of colour
   blindness — but drops stage 1's chroma by roughly half and rotates it off
   cyan into a deep slate-navy. Navy on cream is a warm-neutral pairing; cyan
   on cream is not. The stages stay obviously different, and the chip is
   labelled "Stage 1" in words regardless.

   The per-person framing system (--pf-zoom/--pf-tx/--pf-ty) was hand-tuned for
   9 of 12 speakers but never wired to /board/: board.njk emitted a bare `.pf`,
   so all seven plates computed the identity defaults. Hooks are now emitted per
   slug; these are the tuned values, set against a rendered guide sheet.

/* ==== BACKDROP CORRECTOR CONTAINMENT (user-reported: Niclas Delfs looks washed out) ====
   The .pfx dodge exists to even out a portrait's BACKDROP. Its coverage is set by
   --pfx-sl / --pfx-sr (gradients in from each side). Niclas ran 44% + 44% = 88% of
   the frame, so a contrast(0.30) wash was landing on his face, not just behind it.
   Measured from rendered pixels: his darkest 5% sat at 117 where every other
   portrait ranges 3-23 — i.e. the image had no shadows left at all.
   Célina ran 34% + 34% = 68% and clipped 10.6% of her pixels to white (everyone
   else: 0.2%).
   Pull both back to the frame edges and soften the wash, so the corrector treats
   the backdrop and leaves the subject alone. */
