/* ============================================================================
   Secure Air — Bank Portal design system (spec §14.8). Internet-facing surface:
   shows a bank ONLY its own bookings — never our cost/margin or the upstream
   provider. Shares the console's design language with a distinct TEAL accent and
   a warmer shell, so banks never mistake it for the internal operator console.
   All styling is here (external) — the CSP forbids inline styles. Light + dark.
