/* ===========================================================
   RentMyCFO — design tokens
   Concept: an accountant's ledger, quietly modernised.
   Red is journal ink (used for corrections & closing balances),
   not a flag colour. Numbers are set in tabular mono, like a
   real ledger column. Dark by default — a lit desk lamp over
   a paper ledger at night; switches to a paper-white "day" mode.
