/* =====================================================================
   Ledger — visual language

   The reference is a ruled accounts register, not a web dashboard.
   Figures are the content; everything else gets out of their way.
   Rules are horizontal and thin, columns are ruled only where a reader
   needs to separate money from words, and numerals are tabular so a
   column of amounts lines up digit over digit.
