/* SPONSORSHIP CARD -- the one card component of the home page "Our Sponsorship" section.
   Spec: acutintpro-design-system.md section 2 (09-17-2026). Used by the featured row, the video
   row and every archive row on index.html.

   The card takes the shape of its media and the row makes the heights match: each card grows in
   proportion to --ar (its media's width over its height), so the ratio cancels out of the height
   and every card in a row lands on one height with its flyer or video whole -- nothing boxed,
   cropped, stretched, or dropped below the card beside it.

   Do not edit or remove .flex-container, .flex-item-left, .flex-item-right or .imgwrap to fix this
   section: eight other pages share them, including the align-items:center in flyer.css that drops
   a card below its neighbour here. New classes only. */
