Game Server Readiness Checker
Check the launch basics before players hit a dead server: public address, game port, protocol, Steam/query visibility, version state, password state, and copyable firewall rules.
What this checks
This first pass is a launch checklist and config sanity check. UDP-heavy games cannot be fully proven by a browser TCP probe, so the output separates confirmed config checks from things you still need to verify with an external client.
