/* Rubiks — styles
 *
 * Dark by default, a light theme from the system or from Settings. The
 * layout is one grid: a session column and a stage on wide screens; on a
 * phone the column becomes a drawer and the stage is the whole screen.
 *
 * While a solve is under way (body.busy) everything but the time fades and
 * stops taking input. */
