Choose the package for your runtime. All adapters share the Lumen stylesheet. Use the matching registry command when you want a local wrapper for that framework.

Lumen-specific props and runtime attributes for the Astro primitive. Use the framework differences above and the copyable examples for React composition and Elements attributes; the public adapter types define their supported contracts.
| Attribute | Values | Default | Description |
|---|---|---|---|
| duration | "fast" | "standard" | "slow" | "standard" | Uses the shared duration and easing tokens for keyed layout updates. |
| enterExit | boolean | true | Adds finite entrance and exit fades. Elements uses enter-exit="false" to disable them. |
| data-ui-motion-key | unique string on each direct child | required for animated items | Preserves identity while applications add, remove, or reorder direct children. Duplicate identities skip ambiguous animation. |
| UIPrimitives / reduced motion | Astro runtime / system preference | - | Astro loads the controller only when the group exists. React and Elements own their lifecycle. Reduced motion keeps immediate DOM changes. |
| class, className | string | "" | Merges custom classes with the generated ui-* root classes. |
| ...native attributes | HTML attributes | - | Forwards standard attributes to the root element unless the component consumes them. |
