Networking

Two-phase networking model:

1. Lobby Phase (TCP)

   • LobbyServer manages joins/ready/kick via JSON (ASIO).
   • Once minimum players ready, server dispatches UDP session info.

2. Game Phase (UDP)

   • GameServer runs authoritative simulation.
   • Custom binary protocol (Serializer/Deserializer) keeps clients in sync.
   • Client-side prediction with reconciliation.
