/* Black Tie Agents, house style: an evening in black tie.
   Every page is lacquer night over a slow satin background, with ivory type and
   brass hairlines. Ivory appears only as objects on the table: a phone, a cheque,
   a printed thread. Newsreader Light carries the voice, Hanken Grotesk the
   reading, Plex Mono the small labels. */
