/* Slop of Theseus. One museum: a warm plaster wall, black frames, brass plaques. Colour lives only inside the works.

   space 4/8/12/16/24/32/48 (64 between sections). Display face: Pixelify Sans (a legible pixel face, drawn as outlines,
   so it stays sharp at any size); Micro 5 was dropped after review: its o and e could not be told apart. */
