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. React props follow the same names; Elements use equivalent kebab-case attributes where custom elements expose them.
| Attribute | Values | Default | Description |
|---|---|---|---|
| value | number | required | Sets the final value announced to assistive technology and displayed after the animation. |
| from | number | 0 | Sets the visual starting value. |
| decimals | number | 0 | Sets the number of displayed decimal places. |
| locale | string | browser locale | Formats the value with Intl.NumberFormat. |
| prefix, suffix | string | "" | Adds stable text around the formatted number. |
| duration | "fast" | "standard" | "slow" | "slow" | Uses the shared Lumen motion duration. |
| 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. |
