## Error

```text
Accessing element.ref is no longer supported. ref is now a regular prop. It will be removed from the JSX Element type in a future release.
```

## Symptom
Code (often a library doing `React.cloneElement` / reading `child.ref`) logs `Accessing element.ref is no longer supported. ref is now a regular prop...`. Separately, agents still wrap every new component in `forwardRef` out of habit.

## Cause
React 19 (stable 2024-12-05) passes `ref` to function components as a normal prop. `element.ref` is deprecated (read `element.props.ref`). `forwardRef` is no longer needed for function components and React says it will be deprecated and removed in a future version. Refs passed to class components are still not props.

## Fix
```diff
- const MyInput = forwardRef(function MyInput({placeholder}, ref) {
-   return <input placeholder={placeholder} ref={ref} />;
- });
+ function MyInput({placeholder, ref}) {
+   return <input placeholder={placeholder} ref={ref} />;
+ }
```
TypeScript: type it as a prop, e.g. `{ ref?: React.Ref<HTMLInputElement> }` or `React.ComponentProps<'input'>`.

Reading another element's ref:
```diff
- const childRef = child.ref;
+ const childRef = child.props.ref;
```
If the warning comes from a dependency, upgrade it.

## Verify
`<MyInput ref={r} />` sets `r.current` to the input; the element.ref warning no longer appears.
