 **Goal**: Refactor `ShaderComposer` and WGSL assets to support granular, reusable snippets and `#include` directives. This is an ongoing task to maintain shader code hygiene as new features are added.
 
+### Sub-task: Split common_uniforms.wgsl (Low Priority)
+- **Current**: `common_uniforms.wgsl` contains 4 structs (CommonUniforms, GlobalUniforms, ObjectData, ObjectsBuffer)
+- **Goal**: Split into separate files for granular #include
+  - `common_uniforms/common.wgsl` - CommonUniforms only
+  - `common_uniforms/global.wgsl` - GlobalUniforms only
+  - `common_uniforms/object.wgsl` - ObjectData + ObjectsBuffer
+- **Benefit**: Shaders only include what they need, reducing compiled size
+- **Impact**: Minimal (most shaders only use CommonUniforms anyway)
+- **Priority**: Low (nice-to-have for code organization)
+
 ## Phase 2: Size Optimization (Final Goal)
 
 - [ ] **Task #34: Full STL Removal**: Replace all remaining `std::vector`, `std::map`, and `std::string` usage with custom minimal containers or C-style arrays to allow for CRT replacement. (Minimal Priority - deferred to end).
