The card-back collection

Every premium Thuru 304 card back — real palettes, real motifs, self-contained SVG, grouped by rarity.

All 9 premium card backs, painted by the genuine Thuru 304 CardBack renderer from each catalog entry's palette and signature motif — the T·304 monograms, the Kolam heritage medallion, the Royal Tiger crest, and the animated Obsidian Holographic orbit. Grouped by the catalog's own rarity tiers. Every back is a self-contained SVG — gradients, damask weave, and any animation are inline; no images, fonts, storage, or network. Proof-only.
