Summary
A comprehensive design system built specifically for Pencil MCP that gives you production-ready UI components and tokens. You get a full color system with light and dark modes, typography scales based on Inter and Noto Sans, 4px spacing grid, and pre-built components like buttons, cards, inputs, and avatars. The documentation is thorough about Material Symbols Rounded icons (not Lucide, which matters), shows how to use the G() operation for AI-generated images and Unsplash stock photos, and includes proper text overflow handling with textGrowth settings. It reads like internal design system documentation, complete with tables and JSON specs. If you're building interfaces in Pencil and want to skip the token-definition phase, this gets you to actual design work faster.
