/* ============================================================
   Design system: "The Ledger"
   Grounded in the actual subject of this tool - operators reselling
   goods priced by weight + a wage/making-charge percentage, dispatched
   to Telegram/Bale channels. The visual language borrows from a
   merchant's weighing ledger: ink-dark pages, brass rules, a wax-seal
   stamp for status, and monospaced figures for anything measured.
