I open-sourced a 502-component HTML design kit that works natively with AI coding agents

** DesignKit is a library of 502 self-contained HTML components + 33 full-page designs (mobile + web). Every component uses CSS custom properties (--kit-*). Drop it into any AI agent context — it generates pixel-perfect, on-brand HTML screens in one shot. The problem I kept hitting Every time I wanted to prototype a new app screen, I had two bad options: Describe the UI to an AI — "make a finance dashboard with a balance card, transaction list, bottom nav..." — and get generic, inconsistent output that doesn't match any real design system. Open Figma — spend 30 minutes setting up a frame before writing a single line of code. What I actually wanted: open a file, see a finished UI, ask an AI to convert it to my framework. Done. What DesignKit is A folder of HTML files. That's it.
