Tailwind CSS 4 is a full rearchitecture — new config format (CSS-based instead of JS), new utility patterns. This is a separate effort from the general cleanup.
Scope
- Migrate tailwind.config.ts to CSS-based config
- Update tailwind-merge to v3+
- Audit all utility classes for compatibility
- Test responsive breakpoints
