Uniforms are the pulse.

A fullscreen ShaderMaterial keeps its time, speed, and distortion uniforms on the CPU while GLSL owns the image. The controls expose mutation, recompilation, timing, and teardown as separate contracts.

Compiling the fullscreen ShaderMaterial…

This route covers native ShaderMaterial uniform ownership and rebuild/disposal behavior. It does not claim the official page's exact pixels, device-wide shader performance, context-loss stress, or whole-example fidelity.

The visual is intentionally procedural; changing the variant rebuilds the fragment shader.
