For now I think this is fine, but we really need to figure out what changes are necessary to get proper component-sharing working with our router. We should be able to simply create a shared component containing these routes and share that between <SignIn> and <SignUp>, with the former loading the component through a lazy() boundary.

what's this change doing here? 👀

[panteliselef]

I found the current behaviour a bit buggy, when I added

const usePreloadSignUp = (enabled = false) =>
  useFetch(enabled ? preloadSignUp : undefined, 'preloadComponent', { staleTime: Infinity });
