/* Hover accent. This used to be a conic-gradient ::before at z-index:-1, spun
   by an animated @property angle. Two problems: the angle animation repainted
   the gradient every frame on every card, forever; and :hover applies a
   transform, which makes the card its own stacking context — so the "border"
   painted on top of the card's background instead of behind it and washed the
   text out. The rest of the site signals hover with border + glow, so do that. */
