/* Astra Aviation colours.
   Brand colour is blue, not green: on flight decks green means "normal / safe" (CS 25.1322, ECAM/EICAS), red warning, amber caution,
   magenta active guidance, cyan/blue advisory and selectable. Here too green, amber and red are kept for status only
   (valid, expiring, expired), so a pilot reads them the way they read them in the aircraft, and the brand never competes with them.
   All text pairs meet WCAG AA (4.5:1) in light and dark. */
