# resolved for it) rather than showing "0/0".

# A direct script preload, not the bare "PlanetDefinitions" global class_name
# - the same load-order hazard PlanetSurfaceController's setup_host comment
# already documents: the global identifier is only guaranteed registered
# after an editor/import pass, a direct preload never depends on that.
