/* ==========================================================================
   Beanbucks holo card — pairs with /js/holo-card.js (API docs live there).

   Layers inside .holo-card__tilt (the element that rotates in 3D):
     .holo-card__art    the card PNG/WebP (plate left empty in the art)
     .holo-card__shine  per-design foil, masked by <slug>-foil.webp so it never
                        touches the plate; colour-dodge/colour blended
     .holo-card__plate  the amount + "For <name>" line, drawn live
     .holo-card__glare  a soft light that follows the pointer/tilt

   Everything that moves is driven by custom properties the script writes on
   .holo-card every frame:
     --rx --ry   rotation (deg)           --gx --gy   glare centre (0..1)
     --posx/-y   foil background position --sweep     golden-hour ray sweep (deg)
     --o         effect strength (0..1)   --s         lift scale
   Only transform, opacity and background-position change per frame.

   Plate geometry mirrors constants/beanbucks.js ART.plate (fractions of the
   card); BeanbucksHolo.configure({ plate }) overrides the defaults below.
