/* A warship's plotting room. The page is riveted battleship-grey deck plate
   with stencilled markings and hazard stripes. Your fleet sits on open sea,
   seen from above: grey hulls with a bridge at the stern and a gun turret on
   the pointed bow, burning where they're hit. Enemy waters are a radar
   screen with range rings and a turning sweep: misses are faint returns,
   hits are bright blips, and a ship only shows up once it's sunk. */
