/* =====================================================================
   RELIK A-Z — pop-art redesign
   =====================================================================
   Direction: Warhol's flat, saturated color-blocking meets Moebius's
   luminous gradients. A pastel paper ground throughout, thick ink
   outlines and hard "sticker" drop shadows for structure, and a glossy
   saturated accent color (from each card's own data) doing the actual
   color work — including a soft glow that radiates from the art itself.
   This replaced an earlier warm-dark "museum case" look; the card
   layout and JS underneath are unchanged, only the paint job.
