/* Direction B: the network.
   Rolls sit where their categories pull them, so a roll carried by three
   categories lands between all three. Connections are hairlines, categories are
   set type, and the pictures are clean rectangles. No stamps, no tape, no
   colour: the structure is drawn, not decorated. */
