cloud_noise_v5

Volumetric-cloud noise generator, v5 (Nubis/Schneider style). Builds two foundational noises — Perlin-Worley FBM for the lumpy "cauliflower" base shape and Worley FBM for high-frequency detail erosion — under weather-map control. Writes the 3D cloud density texture.

Bindings (see bindings.yaml): clouds (storage3d rgba16f — the cloud volume), U (read array<f32> uniforms).

Usage: dispatch by identity with compute.dispatchEx("@builtin::systems.volumetrics.shaders.cloud_noise_v5", ...) (storage texture requires resource binding, not positional buffers) — it resolves to the shader's stable guid and auto-compiles on first use (no setup).
