* Renders the 404 error page when no route matched the request, or returns
* `undefined` when a route matched. Returns an empty `400` when the request
* path is over-encoded.
*
* `FetchState` only falls back to an SSR `404.astro`, so this renders a
* prerendered (or absent) custom 404 page: through
* `renderOptions.prerenderedErrorPageFetch` in production, or by rendering
* the page source in dev.
