   Platesea's design, carried over whole: black and white, gold for structure,
   and the photograph as the only colour you are meant to look at. The one
   addition is a little red, for the thing that is live. Three faces doing three
   jobs: a serif for headlines, DM Sans for everything you read, and a mono for
   the small uppercase labels. */
