 The not-found error above will be handled by the same route or nearest parent route that has either a `notFoundComponent` route option or the `defaultNotFoundComponent` router option configured.
 
-If neither the route nor any suitable parent route is found to handle the error, the root route will handle it using TanStack Router's **extremely basic (and purposefully undesirable)** default not-found component that simply renders `<div>Not Found</div>`. It's highly recommended to either attach at least one `notFoundComponent` to the root route or configure a router-wide `defaultNotFoundComponent` to handle not-found errors.
