/* Ride — design system.
   Reference object: the Chinese fleet 三联派车单 (carbonless dispatch slip):
   pale blue-grey stock, deep ink-blue printing, one red chop. Field labels are
   wide-tracked and small; values are large. Times use tabular monospace so a
   column of departures reads like an instrument.

   No webfonts on purpose — drivers are on Chinese mobile networks where
   fonts.googleapis.com is unreliable. Personality lives in the numerals. */
