// Minimal interface that minecraft/ code uses to talk to the network
// subsystem. The concrete implementation lives in app/common/Network/
// (CGameNetworkManager). Same shape as IGameServices: minecraft/ code
// calls the interface; the implementation can sit in a higher layer
// without minecraft/ needing to include its header.
//
// Method names match the existing CGameNetworkManager surface so the
// concrete class can implement the interface without rename churn.
