This is a comprehensive reference for building React UIs with the modern TailwindCSS, Radix UI, and shadcn/ui stack. It covers all three layers: Tailwind for utility-first styling, Radix for accessible primitives, and shadcn/ui for pre-built components you copy into your codebase. The skill includes detailed guidance on when to use each layer, accessibility-first patterns, design token systems with CSS variables, and mobile-first responsive strategies. What stands out is the clear architecture hierarchy and practical decision framework. If you're building component libraries or implementing shadcn/ui components, this gives you the opinionated structure and best practices to avoid common pitfalls with dark mode, theming, and accessible component composition.
