 * Sign-in screen.
 *
 * Modelled on the sign-in screens of the other Konekallio applications
 * (konekallio-kai, konekallio-messaging): a light grey page, one bordered white
 * card, a dark square mark above the name. The slate ramp comes from
 * app-chrome.css, which the login layout loads first; the indigo of that file
 * is kept for focus rings only, where it matches the signed-in app.
 */

/*
 * app-chrome.css locks the document so the signed-in shell can own the only
 * scrolling region (#521). This page has no such shell — it is one card that
 * has to stay reachable on a short viewport (a laptop in landscape with the
 * on-screen keyboard up), so the lock is lifted here.
