Create a production-quality seamless square PBR base-color texture for a game/3D material library: pale warm-gray terrazzo slab with varied small chips of smoky blue glass, cream limestone, rust-red ceramic, and sparse dark basalt, lightly worn and matte. Orthographic straight-on surface scan, completely flat even diffuse lighting, no perspective, no objects, no border, no frame, no vignette, no shadows, no specular glare, no text. The left edge must tile perfectly with the right edge and the top edge perfectly with the bottom edge. Random convincing aggregate distribution without obvious repetition. Crisp realistic detail suitable for a 2K material map; square 1:1 composition.
