Agent Skills: threejs-node-tsl

three.js node-based shading: Nodes API surface, NodeMaterial and MeshStandardNodeMaterial-style families, TSL (Three.js Shading Language) entry at TSL.html, WebGPURenderer pairing, and core PostProcessing (class) versus addon EffectComposer at a high level. Use when authoring shaders as graphs, using TSL builtins, compute-oriented nodes, or modern WebGPU pipelines; for classic ShaderMaterial GLSL use threejs-materials; for stock EffectComposer passes use threejs-postprocessing; for WebGLRenderer-only tuning use threejs-renderers.
