Checked this against the list conventions and against the resource itself: MIT, @appica/ui-react is live on npm, the Figma community file is real and genuinely free, and the components are built on Tailwind CSS v4 rather than just shipping alongside it. Placement is at the bottom of the 📚 group, and the name and description follow the list's format.

Merging. Thanks for a clean submission — the filled-out template made this easy to verify.
