/* =========================================================================
   mt4-oder-mt5.de — Design System
   Art direction: "Handelsledger" — a finance-editorial aesthetic (think a
   Handelsblatt/FT feature page crossed with a broker's trading ledger).
   Warm paper base, large serif editorial type for headings/numerals, two
   dark "terminal" zones (comparison + final CTA) breaking the paper flow,
   two accent colours with strictly separate jobs: amber = action, teal =
   data/leader. No pill-everything, no thin generic outline icon kit.
   Mobile-first: base rules target small screens, layout upgrades live in
   min-width media queries further down the file.
