The icon-library ingestion approach (split a `.excalidrawlib` into per-icon files + an index, then place deterministically) is credited to [github/awesome-copilot](https://github.com/github/awesome-copilot) (MIT); the scripts here are an independent implementation. The MIT license on this skill covers the skill content; the vendored Excalidraw bundle and fonts remain under their own (MIT / respective) licenses, and any user-supplied icon libraries remain under theirs. ## Customization **All colors and brand-specific styles live in one file:** `references/color-palette.md`. Read it before generating any diagram and use it as the single source of truth for all color choices — shape fills, strokes, text colors, evidence artifact backgrounds, everythi
