   NRI Outpost — Airports extras
   Currently contains one panel in #airports:
     1) Inter-terminal transfers (.itx)
   (The flight-status board / .fsx was removed — no commercial-friendly
   free data source exists. We may revisit if/when there's revenue.)
   Match the existing site palette — no new tokens introduced.
