   styles.css — The Canadian Debt Clock
   Aesthetic: light + hand-drawn, to match limestonecitybitcoin.com — warm ink
   on white "notebook" paper, Bitcoin-orange identity, Courier ledger numerals,
   uppercase tracked labels, and the doodle "offset-fill" sketch frame. Red is
   reserved for the debt so it still hits hard on white.
