The first real run of the port check found that the crossplay Minecraft
server opens no UDP socket at startup: Bedrock goes through Geyser's
NetherNet transport, and 19132/udp is not open after boot. It is listed as
unboundPorts in that game's test.yaml, with the reason, until a Bedrock
client confirms how players reach it.
