/* ─── What it is ───────────────────────────────────────────────
   Moments, not mechanics. Each beat is one thing Driftwood is like to live
   with, shown with the app's own surfaces (capture card, night screen,
   fragment cards) and a single line. home.css supplies tokens, nav, cards,
   footer and motion. Rowan Ellery's words throughout (synthetic DEV account). */
