3 days	refactor: Shader Asset Integration (Task #24)	skal
	Extracted all hardcoded WGSL shaders into external assets. Updated AssetManager to handle shader snippets. Refactored Renderer3D, VisualDebug, and Effects to load shaders via the AssetManager, enabling better shader management and composition.
3 days	docs: Document asset system technical details	skal
	Adds a section on Alignment, String Safety, and Size Reporting to ASSET_SYSTEM.md.
3 days	feat(assets): Enforce 16-byte alignment and string safety	skal
	Updates asset_packer to align static asset arrays to 16 bytes and append a null-terminator. This allows assets to be safely reinterpreted as typed pointers (e.g., float, const char) without copying. Updates AssetManager documentation to reflect these guarantees.
3 days	docs: Plan Shader Asset Integration (Task #24)	skal
	Updates ASSET_SYSTEM.md to describe shader asset handling. Adds Task #24 to TODO.md and PROJECT_CONTEXT.md to extract hardcoded shaders and integrate them with the AssetManager and ShaderComposer.
3 days	docs: Update project context and re-prioritize task list	skal
	This commit finalizes the session by updating the project documentation to reflect recent progress and future priorities. - Recently Completed: Summarized the finalization of the audio tracker, implementation of build stripping (STRIP_ALL), and resolution of WebGPU stability issues on macOS. - Re-prioritization: Promoted 'Platform & Code Hygiene' (Task #20) to Priority 1 and established '3D System Enhancements' (Task #18) as Priority 2, focusing on Blender integration. - Session Summary: Appended a detailed summary of the session's key achievements to SESSION_NOTES.md.
