/* ========== ANIMATIONS & REVEALS ==========
   Base reveal states now live in css/vibe.css (loaded last).
   Do NOT force `opacity: 1 !important` here — that kills every
   scroll animation. VibeEngine has its own IntersectionObserver
   plus a 4s `no-reveal` failsafe so content can never stay hidden.
