 ### Recently Completed
+- **Shader Asset Integration (Task #24)**: Extracted all hardcoded WGSL strings into `.wgsl` assets, registered them in `demo_assets.txt`, and updated `Renderer3D`, `VisualDebug`, and `Effects` to use `GetAsset` and `ShaderComposer`.
 - **WebGPU Stabilization**: Resolved `WGPUSurface` creation failures on macOS by adding platform-specific `GLFW_EXPOSE_NATIVE_COCOA` definitions and fixed validation errors in the render pass configuration.
 - **Final Build Stripping (Task #8)**: Implemented the `STRIP_ALL` macro to remove non-essential code (CLI parsing, debug labels, iostream) and refined size optimization flags (`-dead_strip`) for macOS.
 - **Minimal Audio Tracker (Task 21.3)**: Finalized a pattern-based audio tracker supporting both procedural notes and asset-based spectrograms with a unified "one-voice-per-pattern" pasting strategy.
