   合流 MergePad · hero3d.css — the home hero: full-bleed three.js night sea (js/ui/hero3d.js) with the
   headline, launch bar and key facts typeset over it. Display classes come from css/type-display.css.
   Poster (assets/hero/poster-*.webp) is always underneath; the canvas fades in over it once the first
   frame is drawn (.h3d.is-3d). Reduced motion / no WebGL / low power → poster only.
