- Consolidated all WebGPU shims and platform-specific logic into src/platform.h.
- Refactored platform_init to return PlatformState by value and platform_poll to automatically refresh time and aspect_ratio.
- Removed STL dependencies (std::map, std::vector, std::string) from AssetManager and Procedural subsystems.
- Fixed Windows cross-compilation by adjusting include paths and linker flags in CMakeLists.txt and updating build_win.sh.
- Removed redundant direct inclusions of GLFW/glfw3.h and WebGPU headers across the project.
- Applied clang-format and updated documentation.
handoff(Gemini): Completed Task #20 and 20.1. Platform abstraction is now unified, and core paths are STL-free. Windows build is stable.

Critical Bug Fixes:
- Fixed pool exhaustion: Tracker slots never freed after use, music stopped
after 8 patterns. Implemented round-robin allocation with cleanup.
- Fixed note name parsing: Added automatic note-to-frequency conversion
in tracker_compiler. Bass and melody now play correctly.
- Fixed timing mismatch: Patterns are 2 seconds but triggered every 4 seconds,
causing silence gaps. Updated SCORE to trigger every 2 seconds.
Improvements:
- Implemented dynamic resource sizing in tracker_compiler: Analyzes score to
determine optimal MAX_VOICES/MAX_SPECTROGRAMS values.
- Created comprehensive rock track: 11 patterns with drums, bass, power chords,
and lead melody over 25 seconds.
- Added 213 lines of asset system documentation with 8 prioritized tasks.
Known Issues for next session:
- Audio quality could be improved (some artifacts remain)
- Note synthesis uses default parameters, needs tuning
- Pattern overlaps might cause voice exhaustion under heavy load
Files Changed:
- src/audio/tracker.cc: Round-robin pool allocation, cleanup logic
- tools/tracker_compiler.cc: Note name parser, resource usage analysis
- src/audio/synth.h: Increased limits to 16 based on analysis
- assets/music.track: 230-line rock arrangement
- doc/ASSET_SYSTEM.md: Comprehensive documentation + 8 tasks
- TODO.md: Updated with recent completions and known issues
handoff(Gemini): Music system now functional but needs quality improvements.
Audio artifacts and synthesis tuning remain. See TODO.md for details.

- Implemented the basic tracker system with runtime support (tracker.h, tracker.cc).
- Added a sample music track file (assets/music.track).
- Created a tracker compiler tool (tools/tracker_compiler.cc) to generate music data.
- Updated CMakeLists.txt to build the tracker compiler and integrate generated data.
- Updated GEMINI.md to reflect new file locations and project context.
