NEVER Do (Expert Anti-Patterns)

NEVER sync all 100 players every frame; strictly use a Relevancy System to sync high-freq data only for players within ~100m. Far players sync at ~5Hz.
NEVER use TRANSFER_MODE_RELIABLE for movement data; strictly use Unreliable to prevent packet backup and network congestion.
NEVER focus on client-side hit detection; strictly use Authoritative Server Validation where the server confirms "Did it hit?" based on state history.
NEVER trust the client for game state; strictly validate all movement, looting, and inventory changes exclusively on the authoritative server.
NEVER run a dedicated server with visuals; strictly use Headless Mode (--headless) or dummy drivers to save massive CPU/GPU resources.
NEVER call RPCs before connection; strictly wait for the connected_to_server signal before attempting synchronization logic.

NEVER pick a fully random center for the Safe Zone; strictly target centers that ensure the new circle is completely contained within the current one.
NEVER allow "Storm Tunneling"; strictly use a Distance-to-Center calculation rather than a simple collision perimeter to prevent skips at low tick rates.
NEVER spawn loot without Object Pooling; strictly pre-instantiate and toggle visibility/collision to avoid GC spikes during dense spawns.
NEVER ignore VisibilityNotifier3D; strictly disable AnimationPlayer, _process(), and heavy AI logic for players that are not visible to the observer.
NEVER print in tight server loops; strictly avoid print() as console I/O is blocking and will tank server performance in high-player-count matches.
