Overview
Tailwind CSS v4 is a complete rewrite of the framework, built on a new Rust-based Oxide engine that's 10x faster. The biggest change: configuration is now done in CSS, not JavaScript. No more tailwind.config.js for most projects.

| Incremental | 450ms | 51ms | 8.8x faster |
| HMR (Hot Module Reload) | 350ms | 12ms | 28x faster |
| Memory usage | Higher | Lower | ~50% reduction |
