   3D CARD KEY ART
   -------------------------------------------------------------------------
   The nine cards use PuzzleIcon3D's lit dioramas instead of the flat paper
   glyphs the 2D landing uses. The art carries its own full-bleed dark stage,
   so the thumbnail becomes a small framed scene: a fixed ink backdrop (to
   avoid a flash of the card surface before the SVG paints), a hairline
   highlight, and a slightly deeper shadow than the 2D cards.

   The pill is re-skinned here because it now sits on dark artwork in BOTH
   themes. The shared rules colour it with --cat-* (dark inks in the light
   theme); these lighter accents keep the Word/Logic/Spatial coding legible
   against the ink stage without changing the 2D cards.
