/*
 * Styling for the QRG simulator control panel.
 *
 * Deliberately nothing like the Highlander console. The two are open side by
 * side while testing, and mistaking the test harness for the real system — or
 * the reverse — is exactly the sort of confusion that ends with someone
 * answering a live tender from the wrong window. Dark chrome, amber accent, and
 * a banner that never goes away.
 *
 * No QVC or Qurate branding is used anywhere. This stands in for their gateway;
 * it must never look like it IS their gateway.
