 * Product card — fills the parent grid cell width (w-full).

 *   1. Image area (fixed height h-36) with coffee-mug fallback icon
 *   2. Name + description (flex-1, grows to fill space)
 *   3. Price + Buy button row (pinned to bottom)
 *
 * Responsive: card width is controlled by the parent grid, not the card itself.
