In December 2025, delivered a comprehensive Berry LED Emulator Animation Framework and supportive documentation/UI, enabling faster authoring, exploration, and reliability of Berry Animations. The work established a scalable foundation for creative LED content and system-wide UX improvements that translate to faster feature delivery and easier onboarding for contributors. Key deliverables include a DSL-based Berry LED Emulator Animation Framework and Animations Suite (including an animation loop manager, APNG exporter, a library of example animations, and a browsable UI) with enhanced color/palette handling supporting common effects (rainbow, breathing, twinkle). Accompanying documentation and UI clarity improvements for Berry Animations streamlined usage and reduced learning curve. Additional packaging and reliability improvements were made by migrating from pako to a local fflate, improving offline stability and build consistency. Major bug fixes and refactors addressed critical animation and UI edge cases: breathing stability in Berry emulator; fix color_cycle when palette is nil; default behavior adjustments for twinkle; renaming palette to colors and cycle_period to period; alignments and strip size adjustments for consistent rendering. Overall impact: clearer developer experience, faster iteration cycles, robust animation tooling, and improved release quality, delivering tangible business value through reusable assets, better docs, and more reliable builds.
