Tailwindcss Fundamentals V4

This gets Claude up to speed on Tailwind v4's complete rewrite: Rust engine, CSS-first config with @theme instead of tailwind.config.js, and the new @utility and @variant directives for custom classes. You'll want it active when setting up v4 projects, migrating from v3, or when you're writing @theme blocks and getting confused about the new OKLCH color format. The source material is thorough on the breaking changes (goodbye theme() function, hello var()) and covers the Vite plugin setup, zero-config content detection, and built-in PostCSS features. Honestly, the CSS-first approach feels cleaner than JavaScript config once you adjust to it, and the 10x performance claim from the Oxide engine is legit in practice.
