Server notes

Dedicated Server AppID 1963720 (distinct from client 1621690). Supports dual connection: PlayFab Game ID crossplay relay and Direct IP (UDP 27015/27016). Headless Linux requires XVFB virtual display & SDL dummy driver to prevent Unity engine crashes. A memory watchdog sending SIGINT before 5.5GB OOM termination ensures zero data corruption.
