Tailwind CSS v4
Verify before implementing: For v4-specific syntax (@theme, @variant, CSS-first config), look up current docs via Context7 (query-docs) before writing code. Tailwind v4 changed significantly from v3 and training data may be stale.
CSS-First Configuration
v4 eliminates tailwind.config.ts. All configuration lives in CSS.
