/* Gift Unfold Overlay (3 sides: TOP + FRONT + LEFT)
   - Non-destructive: only adds overlay on open; does not change prize logic.
   - Assumes your cube faces have classes: .face.top, .face.front, .face.left
   - The actual face images are read from your existing inline styles / CSS vars:
     The script will copy computed background-image from the cube faces.
