/* ==========================================================================
   pum.me — shared stylesheet (subpages + legal; the landing film uses
   css/film.css). Ground-flat doctrine since 2026-07-25: flat grounds,
   solid page-coloured pnav, chapter bands. Satoshi 400/500 only.
   Case rule (2026-07-17): grammatical sentences take sentence case and keep
   their full stops; display fragments (h1 wink, kickers, nav, buttons, FAQ
   questions) stay lowercase with no terminal stop. "pum" is always lowercase.
   No em-dashes in visible copy — colons, commas, parentheses, full stops.
   Copy law (2026-07-20): ALL visible copy obeys the constitution at
   docs/marketing/website-copy-constitution.md (sentence discipline, agency
   verbs, banned cadences). Story page + legal policy exempt.

/* ==========================================================================
   GROUND-FLAT DOCTRINE (ported from proto, 2026-07-25)
   The material-budget rethink (manifest 2026-07-21/22), propagated to the
   production subpages. Pages opt in with class="ground-flat" on <html>:
   - no animated canvas — flat ground, the material budget spends motion
     nowhere on subpages
   - solid page-coloured full-bleed nav + burger sheet (two-chromes rule:
     never compete with Safari 26's liquid-glass chrome)
   - Safari 26 shape: fixed elements carry NO background/backdrop-filter
     (the chrome-tint sampler reads them); ink lives on absolute children
   - chapter bands: transparent sections sit on the html ground (#E6F4F7),
     .section-paper is the calm near-white body chapter, .band-rich is the
     punchy closer chapter
   - glass calms to soft solids: blur has nothing to refract on flat ground
   The legacy .nav / #iridescent-bg system above remains ONLY for the old
   index.html, which the proto film replaces at ship.
