   Technique: layer two backgrounds via background-clip. The inner layer
   (padding-box) is a solid card color; the outer layer (border-box) is the
   conic rainbow. A transparent border exposes only the conic layer, so the
   rainbow appears as the border — NOT a tint on the card interior.
   Uses @property so the angle animates smoothly. Graceful fallback on
