   ft-explainer.css — "The Fragmentation Tax, explained."
   /fragmentation-tax/explainer · August 2026

   From the Claude Design explainer handoff. Load order is
   tokens.css -> site.css -> fragmentation-tax.css -> this file ->
   v12.css (last). The campaign shell (.ft-wrap / .ft-sec /
   .ft-eyebrow / .ft-h2 / .ft-sub / .ft-close* / .ft-form) comes
   from fragmentation-tax.css and is NOT restated here; everything
   below is the explainer's own blades, prefixed .fte-*.

   MERGE NOTES — what changed from the handoff, and why (design
   guide §09 v1.2, which this page opts into via <body data-v12>):

   · RADIUS. The handoff specifies 8 / 14 / 16px corners. Every one
     of them is written here as var(--radius-*), so the v1.2 purge
     squares the whole page in one declaration. NO LITERAL RADII —
     a literal is exactly how a page half-squares, which §09
     adjudication 11 calls worse than either system. That includes
     the film: R9 exempts films because they are built on literals,
     but the campaign's own film (ft-film.css) carries zero radii,
     so this one squares with the page rather than fork the tier.

   · TYPE. The handoff's 700-weight headings are not restated —
     [data-v12] takes h1 to 600/-.03em and h2/h3 to 500. The two
     display-scale headlines that must hold 600 carry two classes
     so they outrank the element selector (same trick as
     .ft-close .ft-close-title).

   · MONO. var(--font-mono) resolves to Montserrat under v1.2
     (R1b/M1c), so the chip and numeral roles here ask for
     tabular-nums instead — the one job mono was doing for them.

   · EYEBROWS. The handoff's 11px/.18em label is replaced by the
     campaign .ft-eyebrow (11.5px/.15em + E2 square tick) everywhere,
     chapter openers included — they were numbered at first, and the
     numbering was dropped 18 Aug 2026.

   Colour discipline, inherited from the landing page: red
   (--bud-red) marks the problem state only — the film's boundary
   beat and chapter 01. Everything downstream is violet.

/* ═════════ THE FILM — 30 seconds ═════════
   Staged exactly like the product-page overview films: a motif-backed
   16/7.2 frame under a normal section head, with the shared chrome from
   site.js doing the rest — window.BudFilmProgress injects the timeline
   line on the top edge (.bud-film-prog) and window.BudFilmNav injects
   the back/forward controls (.bud-film-nav), the legibility veil
   (.bud-film-veil) and the [data-film-beat] motif dim. All four are
   styled globally in site.css, so nothing about them is restated here.

   Beat state is one attribute on the stage: data-beat="0".."5", and
   this file owns every visual it drives. The markup ships at beat 5, so
   no-JS and reduced motion both land on the finished plane —
   ft-explainer.js only ever rewrites the attribute. */

   carousel keeps its own surface). Here the block is page content on a

   Cards, not a ruled table. The rule-separated version put this block

   the titles wrapped in a narrow one. So: K2 edge-accent cards (§09 R5),
   a display numeral carrying the enumeration, and the title column widened
   to the width the titles actually want.

   The accent edge is the section's argument, not decoration: the guide's

/* ═════════ THE NEWSLETTER BAND ═════════
   partials.js mounts the sign-up as a standalone .nl-band above the footer
   rule on any page without a closing .cta-panel — which is this page, since
   the guide gate IS its conversion. site.css gives that band `padding: 0 0
   56px` on the stated assumption that "spacing above comes from the
   preceding section's own padding". True on /poc, /contact, /partner and
   /leadership, whose last section ends in 64px of its own padding. NOT true
   here: .ft-close is a full-bleed motif blade whose padding lives inside
   .ft-close-in, so the grid's hard bottom edge lands flush on the sign-up
   row and reads as an overlap. Matching the band's own bottom value centres
   the row in its space. Scoped to .ft-page rather than fixed in site.css so
   the four shipped pages above keep the spacing they were designed with. */
