 * Layout: a label column and a reading column on a 12-column grid. The
 * portrait figure in the hero is the one object allowed to leave the plane;
 * everything else stays flat and quiet around it.
 *
 * Colour: ink on a neutral paper, one burnt-orange accent sampled from the
 * wood behind the portrait, and a dark stage for the figure.
 * Type: Archivo (wide) for display and interface, Newsreader for reading,
 * IBM Plex Mono for dates, venues and captions.
