design-ai drops DESIGN.md library for AI agents

The "hallucinated UI" problem remains a significant hurdle for AI-generated frontends, and DESIGN.md offers a simple, low-overhead solution by standardizing visual constraints in a format agents prefer over complex JSON. The library includes extractions from major platforms like Anthropic and Vercel, demonstrating a recursive loop where AI builds the tools that improve its own output. This MIT-licensed project is well-positioned as an open-source "Design System as Code" standard that integrates seamlessly into modern AI coding workflows.
