/* ============================================================
   SNACKIT — MOBILE EXPERIENCE LAYER
   Loaded after style.css + pages.css. Touch-first polish:
   · immersive full-screen menu with staggered choreography
   · tablet nav fix (721–1024px had no menu at all)
   · press-state micro-interactions (native-app feel)
   · scroll-reveal system (compositor-only transforms)
   · scroll progress bar, dock/CTA collision fix
   All effects respect prefers-reduced-motion.
