/* Terrill Finances
   ------------------------------------------------------------------
   Design intent: this is a note left on the kitchen bench, not a bank
   dashboard. The due date leads in serif; the amount is secondary. No
   running total anywhere -- a big outstanding figure is the thing that
   makes her close the tab. Overdue is ochre rather than red for the
   same reason: "look at this", not adrenaline.
   Colour is never the only signal; the words always say it too.
