  The root path is never accessible in Plausible.Cloud because it is handled by the upstream reverse proxy.

  This controller action is only ever triggered in self-hosted Plausible. It redirects the user to /login where `PlausibleWeb.RequireLoggedOutPlug` plug kicks in. If they are already logged in, they are redirected to /sites, otherwise they'll see the /login page.
