/* ══════════════════════════════════════════════════════════════════════════
   SHIVAA v125 — owner-selected film showcases on the homepage:
   · The Revolving Case (preview Way 17) — a draggable 3D ring of the four
     films: drag/throw, magnetic snap, only the front film plays.
   · The Gold Thread (preview Way 12) — a scroll-drawn gold thread that
     weaves through the four chapters and ignites each film as it passes.
   · The Reel — full-screen film player (sound, swipe, auto-advance) with a
     zoom-from-origin transition.
   Self-guarding: every rule is namespaced sv-; nothing here touches
   another layer. au-lite / prefers-reduced-motion still all ambient motion.
