`react-refresh/only-export-components` rejects a non-component export from a component module, so `parseObjectDraft` could not live beside `JsonObjectInput`. It is a pure transform, which puts it in `utils` under the `lib`/`utils` rule anyway. Also render the metadata hint's inline literals through `<Code>` rather than markdown backticks, which a Mantine `Text` shows verbatim.
