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 |
|---|---|---|---|
| rows | number | 4 | Sets the visible text rows. |
| 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. |
