Reference to procedural shader
Make a shader match the texture.
Generate a seamless reference with the existing texture pipeline, then let a measured GLSL harness run ten DeepSeek improvement passes. Each pass is rendered and scored against the reference for palette, grain, structure, and tile seams.
Generate a reference to begin.
