/* ============================================================
   網站判頭 WebForeman — construction-foreman website brand.
   (WORKING NAME — rename = folder + strings before real domain.)

   Art direction: 貼地・硬淨・抵到笑. Flat safety-yellow #FFD100 +
   near-black ink on warm site-office paper. Hazard-stripe rules,
   dashed "site-plan" borders, spec-sheet mono. Type = Anton
   (condensed poster Latin) × Noto Sans TC 900/400 × IBM Plex Mono.
   ONE dark band (final CTA). No gradients, no emoji, no glow.

   Motion contract (accessible-motion-layer):
   - default CSS = final, fully visible state (no-JS safe)
   - ALL motion styles live under html.motion
   - foreman.js adds .motion only when prefers-reduced-motion allows
