/* Datapinot — FerriteMem
   One stylesheet for every page.

   THE COLOUR SYSTEM, which is the whole of it:
     teal   a measured strength
     ochre  something incomplete, or a curve giving ground
     brick  a floor, or what a failure costs
   The same three carry tags, figures, and each section's accent — so the page's
   structure says the same thing its numbers do. */
