/* Rehearsal Room, design B3: the editorial spread. Duncan's direction: keep the simple styles
   and the fonts, yellow as the base backdrop, white and black type over it, an editorial look,
   and a desktop that is a real composition rather than a stretched phone.
   The page is a yellow sheet. Reading surfaces (the script, a table, a form) are white blocks
   laid on it. Type is black; on black blocks it is white. There is no third colour: emphasis
   is weight, size, a rule, or a black block. Desktop is a three-column spread: the session puts
   the slugline, cast and record in the left margin, the script in the centre on a white sheet,
   and the coach's notes in the right margin. Phone stacks the same parts in reading order.
   Dark is the night edition: black sheet, white type, yellow where black blocks were. */
