/* Glassmorphism cards.

   Each card carries the accent of the tool it opens, so the color a visitor
   clicks is the color that greets them on the other side. The hue is set once
   per card as a variable — the mark and the CTA read from it. `-rgb` is the
   same hue unwrapped, because rgba() needs the channels loose to vary alpha.

   `--card-ambient-rgb` is the wash behind the card (cursor glow, hover shadow).
   It follows the accent by default, but stays separate so a card can carry a
   hue that only works as a mark and not as a full-card tint. */
