The default login form references images and styles from the starter.content. We should avoid that, since the default login form can be deployed in other scenarios as well. Instead, we should:
- provide a standalone login page for the o.a.s.auth.form bundle
- move the current login form to o.a.s.starter.content bundle
The intent is to have a good-looking form for the starter content but also one that does not look broken for auth.form.
We should also add an HTML comment to the default login form pointing to customisation possibilites.
