/*
  FinTrack — visual identity: "The Ledger"
  A financial journal feel: warm paper background, deep forest green
  as the primary ink, aged-brass as the single accent. Serif numerals
  for anything that's a monetary amount (the way a printed statement
  sets its figures apart), sans-serif for interface chrome.
  Avoids: uniform rounded-card-with-shadow kit, all-caps labels,
  gradient washes, arrow-suffixed buttons.
