3 days	fix(3d): Correct shadow bug with non-uniform scale	skal
	- Changed the floor object in 'test_3d_render' from SDF BOX to rasterized CUBE. - This prevents the non-uniform scale of the floor from breaking the scene-wide SDF query used for shadow calculations. - The lighting and shadows now render correctly in the more complex test scene.
3 days	test(3d): Enhance test scene with more objects	skal
	- Updated 'src/tests/test_3d_render.cc' to populate the scene with a large floor and 30 randomly placed objects (spheres, boxes, tori). - This provides a more complex environment to verify the new shadow mapping implementation.
3 days	feat(3d): Add scaffolding for visual debugging (Task #18a)	skal
	- Added 'src/3d/visual_debug.h/cc' to implement wireframe rendering. - Integrated VisualDebug into Renderer3D with a static global toggle. - Added '--debug' command-line option to 'demo64k' and 'test_3d_render' to enable wireframes. - Updated 'src/gpu/effects/hybrid_3d_effect.h' to expose the debug setter (reverted later as static method used). - Ensured full cross-platform compatibility (native and Windows) for the new debug module. - All code guarded by STRIP_ALL for final release.
3 days	fix(build): Add compatibility for older wgpu-native headers	skal
	- Added preprocessor definitions for 'WGPUOptionalBool_True' and 'WGPUOptionalBool_False' to ensure successful cross-compilation against the older wgpu-native headers used for the Windows build. - This resolves the build failures in the Windows CI/check script.
3 days	refactor(platform): Encapsulate state in PlatformState struct	skal
	- Replaced all global static variables in the platform layer with a single PlatformState struct. - Updated all platform function signatures to accept a pointer to this struct, making the implementation stateless and more modular. - Refactored main.cc, tests, and tools to instantiate and pass the PlatformState struct. - This improves code organization and removes scattered global state.
3 days	feat(platform): Fix high-DPI scaling and add resolution option	skal
	- Fixed a 'squished' viewport bug on high-DPI (Retina) displays by querying the framebuffer size in pixels instead of using the window size in points. - Centralized window dimension management within the platform layer. - Added a '--resolution WxH' command-line option to allow specifying a custom window size at startup. This option is stripped in STRIP_ALL builds. - Updated all test and tool executables to use the new platform API.
4 days	feat: Add seamless bump mapping with procedural noise	skal
	- Replaced white noise with smooth value-like noise. - Implemented periodic texture generation (seam blending). - Integrated bump mapping into Renderer3D using finite difference of displaced SDF. - Updated test_3d_render with noise texture and multiple SDF shapes (Box, Sphere, Torus).
4 days	feat: Implement hybrid rendering with SDF primitives	skal
	- Added SDF logic for Sphere, Box, and Torus in WGSL. - Implemented hybrid normal calculation (analytical for sphere, numerical fallback). - Updated Renderer3D to dispatch object types to shader. - Updated test_3d_render to display mixed SDF shapes (Sphere, Torus, Box). - Added BOX to ObjectType enum.
4 days	feat: Implement 3D system and procedural texture manager	skal
	- Extended mini_math.h with mat4 multiplication and affine transforms. - Implemented TextureManager for runtime procedural texture generation and GPU upload. - Added 3D system components: Camera, Object, Scene, and Renderer3D. - Created test_3d_render mini-demo for interactive 3D verification. - Fixed WebGPU validation errors regarding depthSlice and unimplemented WaitAny.
