# On Docker Desktop (macOS/Windows), host.docker.internal resolves to the
# host machine. We detect this and configure MAVLink + DDS to send to the
# host IP instead of localhost (which stays inside the container VM).
#
# On Linux with --network host, host.docker.internal does not resolve and
# PX4 defaults work without modification.
