 * One pinned sequence (`.hx`): the hero video tilts into a panel and separates
 * into three tinted glass layers, then a deck of rounded cards slides over the
 * stage. Everything below is the finished, static layout; pinned and
 * in-progress states apply only under `html.hp-motion`, set by the inline boot
 * script unless the visitor asked for reduced motion. home.js writes geometry
 * and adds state classes (`is-active`, `is-on`, `is-lit`).
