/**
 * Home = the voyage. One long timeline: hero → profile → asteroid belt with a
 * beacon per project → stack constellation → contact portal.
 *
 * Two rendering modes from the same markup:
 *  - default (no JS, no WebGL, reduced motion): normal stacked sections
 *  - `html.cinema` (set by voyage.ts): sections become fixed overlays,
 *    the wrapper's height becomes the scroll timeline.
