   Key idea:
   - The available height of the row is H = 100dvh - header - footer - row-pad*2

   - Each card must also fit 4-across: width <= (100vw - page-pad*2 - gap*3) / 4
   - Cards maintain 9:16 portrait aspect ratio
   We achieve this purely in CSS using aspect-ratio + height + max-width.

     *      → prevents cards being taller than the screen
     *   B) Width to fit 4 cards side-by-side with gaps
     *      → prevents horizontal overflow
     *   C) Absolute max cap of 210px
