Native WebGPU is based on the pinned official materials example. The deterministic local texture replaces the official UV-grid and alpha-map assets; Inspector presentation, exact layout/camera timing, device/compiler breadth, performance calibration, and whole-example fidelity remain separate. Add ?backend=webgl for the explicit reference lane.
