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.
