The brocade pattern repeats exactly across the tile edges. Seamless tileable texture for a game material, top-down orthographic view, perfectly flat even lighting with no directional shadows, no highlights and no vignette, uniform detail density from edge to edge so the tile repeats without visible seams, albedo map look, physically plausible scale, crisp detail. Square tile. No text, no letters, no numbers, no labels, no logos, no watermark, no UI.","aspectRatio":"1:1","idempotencyKey":"a-new-uuid-per-run"}'
