Framework example
Choose Astro, React, or Elements to compare native usage against the shared visual output. Each example assumes the framework-level setup is already complete.
Framework usage
Switch targets to compare the adapter code. The preview stays visually stable because all three packages share the same tokens andui-* class contract.---

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 |
|---|---|---|---|
| image | ImageMetadata | required | Sets the source image processed by astro:assets. |
| alt | string | required | Sets the alt text, or pass ariaHidden for decorative covers. |
| mode | "card" | "detail" | "card" | Switches between the card crop and the contained detail frame. |
| hover | boolean | false | Lifts the cover on hover (respects reduced motion). |
| showBottomGradient | boolean | false | Overlays a bottom-to-top fade for legible captions. |
| 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. |
