   site3 — "Scroll Through the Product"
   Faithful replica of the Synopsis app shell. Tokens verbatim from the app.

   SCROLL MODEL: full-viewport scroll-snap pages (one page per gesture; never
   rest between two). Animations are 100% time-based (rAF clock), decoupled
   from scroll — see app.js. No pinned tracks, no scroll scrubbing.
