- Created Vite 6 project with React 18 and TypeScript 5 template
- Installed zod, react-hook-form, @hookform/resolvers (production)
- Installed tailwindcss @tailwindcss/vite (Tailwind v4 via Vite plugin)
- Installed vitest, @testing-library/react, @testing-library/dom (dev)
- Configured Tailwind v4 via @tailwindcss/vite plugin in vite.config.ts
- Set src/index.css to @import "tailwindcss" (no postcss/tailwind.config.js)
- Created minimal App.tsx with Tailwind classes, .gitignore
