The project involved creating custom tooling for frame-by-frame animation editing, mapping brand colors to ANSI codes that work across different terminals and accessibility settings, and using Ink (React for terminals) to render animations without flickering. The team treated color as a semantic system rather than literal RGB values, made the animation opt-in for accessibility, and separated frame content from styling to create a maintainable architecture. A designer built the initial prototype using GitHub Copilot and contributed their first engineering PR, later open-sourcing the ASCII animation tool. ## Full article daily.dev links to this article rather than hosting it.
