### `ErrorBoundary`

```ts
ErrorBoundary: (props: ErrorBoundaryProps) => JSXElement
```

Creates a boundary for descendant mount and post-mount render/commit errors,
including content materialized through a portal host.

### `ErrorBoundaryFallbackRender`

```ts
ErrorBoundaryFallbackRender: (error: unknown, reset: () => void) => ErrorBoundaryFallbackValue
```

Renders a fallback for the caught error; call `reset` to retry the children.

### `ErrorBoundaryProps`

```ts
ErrorBoundaryProps: any
```

Props for {@link ErrorBoundary}.

- `children`: Optional children slot

- `fallback`: Static fallback content, or a render function receiving the error and a reset callback.

- `key`: Optional key for keyed lists (string | number | symbol for internal frames)

- `onError`: Called with the caught error when the boundary trips.

- `resetKey`: Changing this value resets the boundary, re-rendering the children.
