/*
 * Sign-in shell.
 *
 * This exists because of a wrong assumption the login page was built on: the
 * markup uses Paper Dashboard's login classes — `.full-page`,
 * `.full-page-background`, `.full-page:after` — and **this build of
 * paper-dashboard.min.css does not define any of them.** It carries only
 * `.wrapper.wrapper-full-page`. So the background div was 0px tall, the wash
 * had no `content` and never painted, and the photograph behind it was never on
 * screen: a white void with a card floating in it, which is exactly what it
 * looked like.
 *
 * Rather than depend again on rules that are not there, the page owns them.
