 * `!important` is load-bearing here, not laziness.

 * the user-agent default. `#login { display: grid }` below has specificity (1,0,0) against
 * this rule's (0,2,0), so without this the login screen stays on screen after signing in
 * and the dashboard renders below the fold - which looks exactly like "nothing happens".

 * added later, rather than leaving the same trap for the next ID-scoped rule.
