/* ═══════════════════════════════════════════════════════════════
   HoloCard — VMax-style holographic NFT card
   ───────────────────────────────────────────────────────────────
   Layers:
     1. Card base (perspective container)
     2. Rotator (3D transform driven by --rotate-x / --rotate-y)
     3. Front face: image + shine + glare + meta
     4. Back face: metadata layout (rotateY 180deg)

   Holographic effect inspired by Pokemon VMax cards:
     - Subtle, slow-moving rainbow gradient (large background-size)
     - Pronounced diagonal texture lines
     - Cursor-tracking radial highlight
     - color-dodge + overlay blend modes

   Expand-to-center:
     - Click triggers FLIP animation: translate + scale + rotateY(180)
     - Backdrop overlay with blur
     - ESC / backdrop click to collapse
