Nebula Gambit Shared Card Back

Generated from: Portrait collectible card back, perfectly symmetrical vertical mirror design for face-down play, premium tactile tabletop card game art, standard poker card proportions. Full-bleed deep navy and violet nebula background with teal wisps and a fine star field. Ornate antique-gold geometric filigree border set well inside the edge with a generous safe margin, matching the border language of the card face, with no important detail near the crop edge. Center: one large symmetrical emblem of a radiant celestial sigil - a constellation mandala with a central eight-pointed star and orbiting planets arranged in perfect balance, fine sacred-geometry linework, subtle gold glow. Tactile matte texture, rich contrast, print-ready, no text, no watermark, no fine detail at the extreme edges.
