This is a comprehensive reference for UI/UX decisions during code review or generation. It covers 152 rules across animations, typography, audio feedback, and UX patterns, each tagged with priority levels from critical to low. The categorization is genuinely useful: you can quickly check whether springs or easing curves fit your use case, verify exit animation setup in AnimatePresence, or validate that your audio feedback respects accessibility standards. The rules are concrete, like "timing-under-300ms" or "pseudo-over-dom-node", making them easy to search and apply. Most valuable when you're implementing motion or need to systematically review interface code against established patterns rather than guessing at best practices.
