/**
 * ========================================
 * POSTER CARD FIX - NETFLIX-STYLE LAYOUT
 * ========================================
 * 
 * PROBLEM DIAGNOSIS:
 * - Images weren't filling cards due to image-rendering properties
 * - Aspect ratio container wasn't enforced properly
 * - Object-fit: cover was being overridden
 * - Hardware acceleration transforms were hiding images
 * 
 * SOLUTION:
 * - Enforce 2:3 aspect ratio on container
 * - Use object-fit: cover without aggressive rendering
 * - Remove transform: translateZ(0) that was breaking display
 * - Position: relative on container for absolute badges

/* ===============================================
   WHY THE ORIGINAL ISSUE HAPPENED
   ===============================================
   
   1. IMAGE-RENDERING PROPERTIES
      - image-rendering: crisp-edges was breaking display
      - Browsers don't support all values consistently
      
   2. TRANSFORM: TRANSLATEZ(0)
      - While good for GPU acceleration, it was hiding images
      - Combined with backface-visibility created conflicts
      
   3. MISSING ASPECT-RATIO
      - Without enforced aspect ratio, containers collapsed
      - Images couldn't maintain 2:3 poster proportions
      
   4. WILL-CHANGE: TRANSFORM
      - Overused will-change causes rendering issues
      - Should only be used during animation
      
   5. OBJECT-POSITION NOT CONSISTENT
      - Some had 'center', some had 'center top'
      - Posters need 'center top' for better framing
      
   SOLUTION SUMMARY:
   - Clean HTML structure with semantic classes
   - Aspect ratio enforcement on container
   - Simple object-fit: cover without exotic properties
   - Proper z-index stacking for badges
   - Skeleton loading state
   - Full carousel compatibility
