/* Card thumbnail — optional image bleed at top of card */
/* .card-thumb carries the negative margins that bleed the image past the card's own
   padding. The 16:9 ratio itself lives on the nested .card-thumb-ratio element rather
   than on .card-thumb directly — percentage padding-top always resolves against the
   containing block's width, and .card-thumb's own containing block is .card's un-bled
   content box (narrower than .card-thumb's final bled-out width), so putting the ratio
   trick directly on .card-thumb computes it against the wrong, smaller width. Nesting
   one level deeper makes .card-thumb-ratio's containing block .card-thumb's own
   (already bled) width, which is the one we actually want the 16:9 to apply to. This
   also sidesteps any cross-browser inconsistency in how the native `aspect-ratio`
   property is resolved on a flex item that also has negative margins. */
