The `Login` is both in `client/pages/Login.svelte` and also in `client/components/Login.svelte`. The
one in `pages` is more like this demo and simply uses the `component`.  The reason for the split is
so you can prompt for a login with a `Modal` in situations where tearing the user away from what
they're viewing might be wrong.  A good example of this is if people are watching a video but need
to log in to comment or chat.
