/* ============================================================
   Tsinglan iGEM Wiki — Cinematic homepage ("you NAILed it")
   ------------------------------------------------------------
   Structure inspired by 2026 GreatBay-SCIE's homepage
   (loader → painted hero → scroll story chapters → product),
   but every colour / font / illustration is Tsinglan's own:
   deep navy + mustard + cream + coral, Playfair Display,
   shells, waves, nails, peptides.

   Pairs with:
     - wiki/pages/home.html      (markup, inline SVG art)
     - static/js/home-cinema.js  (loader + scroll choreography)

   Animation contract:
     JS drives CSS custom properties only —
       --anim-y   vertical offset (px)
       --anim-x   horizontal offset (px)
       --anim-s   uniform scale
       --anim-sy  vertical scale
     plus opacity and stroke-dashoffset. Every animated element
     keeps its own base transform and folds the vars into it, so
     static (no-JS / reduced-motion) rendering stays correct.
