5 days	opt: Guard debug/seek features with STRIP_ALL	skal
	Ensures that code related to the --seek command line option (simulation loops, silent audio rendering) is completely compiled out when the DEMO_STRIP_ALL build option is enabled, preserving the 64k size constraint.
5 days	feat: Add --seek command line option for fast-forward debugging	skal
	This feature allows developers to jump to a specific time in the demo sequence (e.g., './demo64k --seek 10.5'). It simulates the game logic, audio state (rendering silent buffers), and visual physics (compute shaders) from t=0 up to the target time before starting real-time playback. Audio initialization is refactored to separate device init and start.
5 days	feat: Implement Sequence and Effect system for demo choreography	skal
	Refactors the rendering pipeline into a modular Sequence/Effect system. 'MainSequence' manages the final frame rendering and a list of 'Sequence' layers. 'Sequence' manages a timeline of 'Effect' objects (start/end/priority). Concrete effects (Heptagon, Particles) are moved to 'demo_effects.cc'. Updates main loop to pass beat and aspect ratio.
5 days	build: Add pack_source target to create complete source archive	skal
	Adds a 'pack_source' CMake target that creates 'demo_all.tgz' using tar. This includes all source files, third-party dependencies (even those ignored by git), and submodules, ensuring a self-contained offline build package.
5 days	build: Add DEMO_ALL_OPTIONS to activate all build flags at once	skal
	This adds a single CMake toggle to enable tools, tests, size optimizations, and code stripping, simplifying the development and verification workflow.

5 days	docs: Update contributing guidelines to mandate Windows build verification	skal
	Expands the pre-commit policy to require verifying the Windows build (stripped and packed) if mingw-w64 is present, in addition to the standard native build and tests.
5 days	fix: Resolve macOS build breakage and restore tools audio support	skal
	Updates gpu.cc to handle modern wgpu-native callback signatures (5 args) for macOS while maintaining Windows compatibility. Modifies audio.cc and CMakeLists.txt to ensure miniaudio encoding features are only stripped from the demo binary, not the tools (spectool/tests).
5 days	opt: Disable unused audio formats (FLAC, WAV, MP3) and encoding in miniaudio	skal
	Reduces Windows binary size from 461KB to 356KB (UPX packed) by stripping unused decoders and encoders from the runtime build. Tools (spectool) retain WAV/MP3 support.

8 days	fix(editor): Correct CSS formatting issues	skal
	Cleaned up CSS formatting in style.css to resolve potential parsing errors and ensure proper styling of elements, including buttons and layout.
8 days	refactor(editor): Complete rewrite of script.js for stability and correctness	skal
	Addressed all reported errors by completely restructuring script.js to ensure correct function definition order, fixing the 2x vertical scaling issue in frequency mapping, and confirming SDF logic and audio playback dependencies. - All global variables, constants, utility functions, element declarations, event listeners, and main logic functions are now correctly ordered. - and corrected to use for proper frequency mapping.
8 days	fix(editor): Resolve all scoping, ordering, and scaling issues	skal
	Completely restructured script.js to guarantee correct function definition order and fixed the 2x vertical scaling issue in frequency mapping. - Moved all utility functions (audio, SDF, coordinate/frequency mapping) to be defined before their use. - Corrected and to use for accurate frequency scaling. - Ensured all button element declarations and event listeners are correctly placed at the top of the script to prevent initialization errors.
8 days	fix(editor): Final resolution of initialization and scoping errors in script.js	skal
	Completely restructured script.js to place all global variables, constants, button declarations, and event listeners at the top of the file. This definitively resolves 'Uncaught ReferenceError: Cannot access ... before initialization' errors and ensures proper scoping for all functions, including .
8 days	fix(editor): Resolve button initialization errors	skal
	Restructured script.js to move all button element declarations and their event listeners to the top of the script, immediately after global constants. This resolves the 'Uncaught ReferenceError: Cannot access 'button' before initialization' errors by ensuring elements are initialized before being accessed.
8 days	feat(editor): Implement SDFs for drawing primitives and fix spectrogram clearing	skal
	Refactored drawing primitives in the spectrogram editor to use Signed Distance Functions (SDFs), providing smoother and more flexible shape generation. - : Now stores shape parameters in SDF-friendly world coordinates (frame and log-scaled frequency) and includes a parameter for each shape. - : Completely rewritten to utilize SDFs (, , ) for applying shape effects to the spectrogram data, including attenuation with . - Fixed an issue where the generated spectrogram was not being cleared to zero, ensuring a blank canvas for new drawings.
