Code Block Copy 1 component design & features

This original pattern uses semantic HTML, shadcn-compatible theme tokens, visible focus states, and mobile-first responsive behavior. Its composition is deliberately independent while providing the same practical preview-and-copy workflow as the reference catalog.

The registry endpoint returns editable TypeScript source. Use the preview controls to check compact, tablet, desktop, light, and dark presentations before installing it locally.

Implementation notes

React Server Component compatible unless the pattern requires interaction.
Tailwind CSS v4 and semantic shadcn tokens.
Keyboard focus, reduced motion, and responsive layout support.
