/* ============================================================================
   Stints — runs of tyres, side by side

   A wide table of numbers, which is the honest shape for this: the page is
   read by scanning a column, not by looking at a picture. Everything here is
   in service of that - tabular figures, a monospace face for the pressures so
   the decimal points line up, and enough row height that a finger can find a
   checkbox.

   Colours come from palette.css. No hex here.
