Columbus is a set of React components built on Base UI primitives and styled with Tailwind CSS v4. It's distributed as a shadcn registry: components are copied into your project as source code, so you own them and can change anything.

• Framework-agnostic. Components never import a router or framework API. Navigation is done by styling your own <Link> with buttonVariants.
• Accessible by default. Every component is tested in a real browser, including automated accessibility checks.
• Themeable with tokens. Colors and radii are CSS variables you can override.
