/* ============================================================
   Wallet scanner — field tool styling.
   Scanner: dark, high-contrast for outdoor use, big tap targets.
   Sheet/gate: light, dense, readable for managers.
   Type: system stack (instant, no webfont load on mobile data);
   wallet digits in monospace so they're easy to verify.
