/* ui-prototype/gateway.css — Private Access Gateway.
 *
 * Same tokens as the operator application, so the gateway and the app are visibly one
 * product. No raw colour values; logical properties throughout so FA/AR flip correctly.
 * Deliberately sparse: a public page should carry no more than the product name, the
 * access statement, one sign-in affordance and its honest state.
