/* ==========================================================================
   CARDS — All Card Variations
   
   Five distinct card patterns for article and content display:
   - Card 0: Vertical (classic image-top, text-bottom layout)
   - Card 1: Horizontal (image-left, text-right for lists)
   - Card 2: Minimal (text-only, editorial focus)
   - Card 3: Overlay (text on image with gradient)
   - Card 4: Featured (large format, hero-style card)
   
   Each card adapts to its container and maintains aspect ratios.
