/* Facegammon admin.
 *
 * A dashboard, not a set of pages that happen to share a header: a
 * fixed sidebar for where you are, a topbar for what you are looking
 * at, and one vocabulary of panels, tables, fields and badges that
 * every screen draws from.
 *
 * The palette is the game's - dark leather, brass, cream - because an
 * admin panel that looks like a different product makes the person
 * using it translate between two worlds all day. It is calmer than the
 * game, though: the game is decorated, this is read.
