/*  The sign-in page.

    Kept apart from site.css because it is the one page with no navigation, no client in
    scope and nobody signed in: it is the front door rather than part of the application, and
    it should not inherit layout meant for screens with a header and a menu.

    Shaped after the accounting system's own sign-in so the two feel like one estate: a thin
    information strip, then a lot of quiet space, the product named in the middle, and a
    single card asking for as little as possible.
