   Utility Ledger — stylesheet
   Written as a token layer on top of Bootstrap, not a fight with it.

   Direction: an instrument panel, not a marketing dashboard. The subject is a
   meter reading, so figures are set in a monospace face with tabular figures
   and are always the largest thing in any block. Colour is spent on exactly
   two things — water (teal) and electricity (amber) — and nowhere else.
