/* Overflight subsite — shared system.
   Same palette and scanline-over-gradient atmosphere as the original waitlist
   page. Type follows the app's own design system (Theme.swift): Futura for
   display, monospace reserved for instrument labels and figures only — body
   copy is proportional. Colors mirror Theme.swift exactly: green #46c08a
   (data tint), amber #f0a500 (INCOMING only — never decorative). */
