/* ==========================================================================
   Site V5 system, 2026-09 redesign.

   Replaces pages/veille.css (V4 "La Voix", rejected by the owner on
   2026-09-06). Proof page expertise_marque.html approved 2026-09-06; in
   use on the four expertise pages (file renamed from expertise_v5.css).
   pages/veille.css no longer has a user.

   The scaffolding is stolen from anthropic.com / claude.com (2026-09
   state), structure only, none of their trademark: the two-column hero
   (display claim left, lede and action right), the customer-logo strip
   directly under the hero, hairline meta rows with a right-aligned value,
   the release-card anatomy (title, body, hairline meta footer), the quote
   set off by a single hairline, and the closing panel. Palette, radii and
   the eight-step type scale are the house tokens from style.css: nothing
   is redeclared here.

   Prefix: e-. Namespaced against Bootstrap and against the v- system so
   both files can coexist while only this page uses the new one.

   House rules encoded:
   1. TYPE SCALE. A component takes the nearest style.css token; it never
      declares a literal font-size.
   2. RED BUDGET. At most two semantic uses per page, never decorative.
      marque: the "10" in the rule meta and the emphasised quote phrase.
      signaux: "invisible" in the timing table (the one true loss).
      concurrentielle and crise: none. "agrégé" is always soft ink,
      because aggregation is an availability state, not a loss.
   3. No dark inversions, no decorative numerals. Hairlines live inside
      components only; sections are separated by whitespace.
   4. NO UPPERCASE (owner, 2026-09-06). Labels, kickers and table heads
      are sentence case, normal tracking, like anthropic.com's own.
