/* ============================================================
   Webieai — AI website studio theme (standalone, LIGHT).
   Art direction: 貼地・精準・有信心. White canvas + cool-grey
   #F6F8FB bands, charcoal ink, ONE electric accent pair
   (cyan #2DE2FF → violet #7C5CFF) used decisively — CTAs,
   keylines, marks, gradient-text moments. Text-on-light uses a
   deepened ink variant of the same pair for contrast. White
   browser-chrome windows with soft coloured shadows are the
   signature motif (hero stack + portfolio). Exactly ONE dark
   band: the final CTA. Display = Unbounded + Space Grotesk;
   body = Noto Sans TC, hard 900-vs-400 weight contrast.
   Motion lives in webieai.js behind html.motion +
   prefers-reduced-motion.
