Get this component from a saved library export or the connected CLI. The imports below refer to local files installed in your app.
Import styles/components.css, then styles/theme.css once. Wrap your app in ThemeScope from components/ui/utils so typography, focus and overlays share the theme. The installation guide covers runtime dependencies and React/Next.js setup.

This component consumes your semantic colors, spacing, typography and shape tokens. Import the compiled styles and your theme once as described in Export.
Behavior and accessibility
