/* ============================================================
   Hero story — one long scroll-driven sequence.
   Phase 1 (video): the cheers-at-the-bar clip plays frame-by-frame
   on <canvas> as you scroll, then the phone floats up.
   Phase 2 (screens): the canvas fades to white and a real 3D phone
   showcase flips 360 between the actual app screens.
   Phase 3 (outro): closing line + CTA.
