Enforces design and interaction constraints to prevent common UI anti-patterns in Tailwind CSS projects.

• Validates animation durations (max 200ms for interactions), restricts animations to compositor properties only, and enforces prefers-reduced-motion respect
• Requires accessible component primitives (Base UI, React Aria, Radix) for interactive elements and enforces keyboard behavior standards
• Checks typography rules including text-balance for headings, tabular-nums for data, and prevents arbitrary letter-spacing modifications
• Prevents layout anti-patterns like h-screen (use h-dvh instead), arbitrary z-index values, and animating layout properties
• Reviews files against all constraints and outputs exact violations with code-level fixes
