/* ============================================================================
   YIQIDA customer site — design layer v2
   Direction: "Precision Industrial Editorial"
   - Display type: Barlow Condensed (self-hosted, already on disk)
   - Body type: Inter (self-hosted, already on disk)
   - Palette: warm paper + ink + deep vermillion, hairline rules, indexed sections
   - Motion: scroll-reveal + staggered entry, respects prefers-reduced-motion
   Scope: body.catalog-page ONLY — the ops console (body with #app) is untouched.
   Loaded AFTER style.css so it overrides the legacy customer skin.
