   A single drop shadow reads as a sticker. Two layers read as an object: a tight
   CONTACT shadow that says where it meets the page, and a wide AMBIENT one that
   says how far above it floats. `.card` already lifted 3px on hover but had no
   shadow at all, so the lift had nothing to sell it — the card just slid.

   Two sets, because a shadow is the absence of light: on a dark ground a black
   shadow is invisible, so depth there comes from a lit TOP EDGE (an inset
   highlight) plus a deeper, softer ambient pool. */
