## All tests run headless (no display server). GdTrade, GdTradeLedger,
|
||||
## GdCourierRoute, GdOpenBordersAgreement, GdSharedMapAgreement, and
|
||||
## GdCourierMapView are GDExtension types instantiated via ClassDB.
|
||||
##
|
||||
## GdCourierRoute exposes only getters; tests drive state that requires
|
||||
## pre-set intercepted/era_tier values via GdTradeLedger.from_json().
