   Design tokens
   A ledger, not a dashboard: this app's whole job is recording who
   owes what, since when, under whose name. The palette stays quiet
   (ink on paper) so the one place color earns its keep -- status
   pills, the brand accent -- actually stands out. Money and quantity
   figures get a monospace face and tabular numerals throughout: the
   signature move, because scanning a column of amounts is the most
   common thing anyone does in this app.
