/* ============================================================
   HOMEPAGE VISUAL PASS — artifacts + motion (hand-made paper-ink)
   Additive. Loaded LAST in the cascade (after studio-upgrade.css
   and the inline home-calm block). Owner: creative-director
   (Delacroix) art direction; engineering (Frank) implementation.
   Spec: ~/.hermes/org/briefs/2026-09-21-homepage-visual-pass-design.md

   HARD RAIL #1 — no-JS / reduced-motion safety:
     Every .pp-* / [data-pass] / [data-pass-reveal] element renders in
     its FINAL, visible state by default. There is no opacity:0 or
     hiding transform in base CSS. Animation is progressive enhancement:
     homepage-artifacts.js adds .pp-prep / .pp-run / .pp-draw / .pp-drawn
     / .pp-stamp-in ONLY when motion is allowed, and the JS no-ops
     entirely under prefers-reduced-motion.

   Color rule: tokens only (var(--signal), var(--ink), var(--paper),
   var(--paper-2), var(--muted), var(--leaf)). No new hues.
