/* bragains.co

   One long page laid out like a ledger sheet: a margin column for dates and
   labels, a body column for the record, a note column for annotations. Rules
   carry meaning. A 2px rule heads every register, 1px rules separate records,
   and a double rule closes a register whose entries are complete. Colour is
   spent on links (stamp-ink blue) and on one state, "in service" (green). */
