THREE.JS / WEBGL2 MATERIAL DIAGNOSTIC
Energy stays in the room.
The pinned white-furnace diagnostic makes energy conservation visible: roughness runs left to right, metalness runs top to bottom, and every sphere shares the same filtered radiance.

This route preserves the pinned WebGL2 WebGLRenderer → PMREMGenerator → MeshPhysicalMaterial topology. Exact official layout/pixels, GUI presentation, broad device performance, and whole-example fidelity remain separate.
