/**
 * Wavecon Blind Box - Tier 3-view Image Carousel
 *
 * Replaces old three.js scene. Each tier card now has a 3-image carousel
 * (front/side/top) that rotates every 4 seconds. User uploads:
 *   - /wp-content/uploads/tier-{20,50,100}-front.jpg
 *   - /wp-content/uploads/tier-{20,50,100}-side.jpg
 *   - /wp-content/uploads/tier-{20,50,100}-top.jpg
 *
 * Memory compliance:
 *   - img !important rules
 *   - prefers-reduced-motion handled
 *   - touch-action pan-y !important (iOS Safari)
