/* The sign-in page.

 * Split in two: the form, and a room of cats solving itself beside it. The art
 * is the second column rather than a background image behind the inputs,
 * because text over moving artwork is a contrast problem that no amount of
 * overlay really fixes - and on a phone the art is dropped entirely rather
 * than shrunk into a strip nobody can read.
