/* Cheque Tracker — visual identity: a calm, offline finance ledger.
   Deep emerald brand (bluer/deeper than the workbook's "Passed" green so the two never read
   as the same thing), green-tinted neutral surfaces, serif for headings (brand + section
   titles), system sans for everything functional. No network fonts — must run from file://.
   --ct-text and --ct-track are read by js/charts.js; --ct-status-*-bar by js/views.js. */
