/* =============================================================
   Vindexa — Homepage v4 — themed (light/dark) + scroll reveals
   ----------------------------------------------------------------
   Color discipline: near-white as default, cream as one accent
   (The File section), dark as structural anchor (How it works),
   deep forest as the closer. Gold reserved for the seal + the
   $5,000 callout — nowhere else.

   THEMING — every section reads from semantic variables:
     --bg / --bg-accent / --bg-card / --bg-hover / --bg-anchor
     --text-strong / --text-body / --text / --text-muted / --text-faint
     --accent (forest in light, sage in dark), --gold, --risk
   html[data-theme="dark"] re-maps them. Surfaces that are
   "physically" colored — the Golden Record file card (paper),
   the closing (forest), the seal (gold) — stay fixed in both
   themes; they are objects, not chrome.

   Type discipline: three clear tiers.
     Tier 1 — .t-section : section headlines, the largest move
     Tier 2 — .t-subhead : confident subsection heads
     Tier 3 — body copy  : paragraph-scale, readable
     plus  — .t-eyebrow  : tiny mono metadata
