rjsf-team/react-jsonschema-form ? reverse-engineered prompt

Build me a React form builder that can take a JSON Schema and turn it into a working web form automatically.

I want a clean demo site where I can paste or edit a schema, see the form update live, fill it out, and get the resulting JSON back. It should handle validation, required fields, different input types, and a few common schema patterns like objects, arrays, and nested fields. Please also make it easy to swap the look and feel with a few popular themes, so the same form can match different UI styles without changing the schema.

If it helps, look up the current docs online and match the project’s real behavior as closely as possible. Keep the code organized so it feels like a reusable library, not just a one off demo.
