The full set of AirspaceType values, in declaration order.
Use as the single source of truth for value-side iteration (e.g. building a
lookup table keyed by airspace type) or with isAirspaceType to
narrow an external string into the union. The as const satisfies brand
keeps this array in sync with the type at compile time - adding a new
union member without updating the array fails the build.
