   STANDARDIZED CARD SYSTEM (Layout-Based)

   New card system using layout variants:
   - poster: Dark overlay with background image
   - picture: Standard card with image on top
   - horizontal: Image + text side-by-side
   - title: Minimal title-only card
   
   Uses Bootstrap utilities + minimal custom CSS
