+Shader code (WGSL) can also be managed as assets.
+1. Create `.wgsl` files in `assets/final/shaders/` (or similar).
+2. Add them to `assets/final/demo_assets.txt` with compression `NONE`.
+   Example: `SHADER_COMMON, shaders/common.wgsl, NONE`
+3. In C++, retrieve them using `GetAsset()`. Since they are binary blobs,
+   construct a `std::string` or `std::string_view` using the returned pointer
+   and size.
+4. Register them with the `ShaderComposer`.
