GenUI Clinic — json-render catalog and spec review

Paste the json-render catalog that constrains your model and a spec it generated, and get a reliability review: the dangling children and orphaned elements that stop it rendering, the props that should have been enums, the actions it never declared, the state paths nothing writes — plus a corrected spec that is re-validated in your browser and the schema changes that prevent the whole class. A free client-side walk of the element graph runs first, with no model and no sign-in. Derived from @vercel-labs/json-render (Apache-2.0), Vercel Labs' generative-UI framework.
