/* Collaborative Intelligence.
   Layout: one centred reading column (680px) with figures that widen symmetrically to 1000px, notes in the right
   margin on wide screens. Colour has meaning and only these meanings: cobalt is the model under test, vermilion is
   the teammate who creates the problem (and a failed test), green a passed test; ochre and slate mark real-world and
   benchmark sources; everything else is ink on white. */
