/* ═══════════════════════════════════════════════════════════════
   ONR RESORT — Design 11: Stacking Celebration (Production)
   ═══════════════════════════════════════════════════════════════

   PHILOSOPHY:
     • Cards stack via position:sticky + z-index (DOM order)
     • NO scroll-snap — it fights sticky. We use CSS scroll-driven
       animations (animation-timeline: scroll()) for the scale/dim
       physics, all on the compositor thread. ZERO JS style mutation.
     • JS only handles: dot tracking, mbar reveal, in-view detection,
       keyboard/dot navigation via scrollTo.
     • The .panel child is the visual surface. The .card itself is
       the sticky positioning box and NEVER transformed.
     • Snap-like behavior: JS detects scroll-end and settles to
       nearest card with scrollTo(smooth) — velocity aware, no fight.

   PERFORMANCE RULES:
     • will-change ONLY on .panel (the thing that scales)
     • opacity + transform ONLY — no layout-triggering props
     • rAF loop for in-view detection ONLY, no style writes
     • scroll listener is passive, no preventDefault
