description: Tailwind CSS v4 rules globs: ["/*.tsx", "/.jsx", "**/.css"] alwaysApply: true

• Tailwind v4 with CSS-first config via @theme {}. No tailwind.config.ts.
• Never hard-code colors. Reference design tokens via utilities (bg-brand-500) or var(--color-brand-500).
• No inline style={{ ... }} for things Tailwind already handles.
• Use cn() / clsx() for conditional classes.
