This is the Refactoring UI book systematized into 52 prioritized rules for Tailwind CSS. It's built for refactoring existing components or writing new ones when you don't have a designer. The rules span nine categories from critical (design intent, hierarchy, spacing) down to polish details, all with Tailwind v4 syntax and fallbacks for v3. What's smart here is the "think first, style second" approach: it forces you to audit what elements actually communicate before touching CSS. If you've read Refactoring UI, this codifies those principles into something Claude can apply consistently. If you haven't, it's a crash course in visual hierarchy through utility classes.
