+// Field order is authoritative from RPCSerializeAuto.lua (Auto.WriteMetroClientInfo):
+// { int32 Id; uint32 LineId; float ElapsedTime; bool IsFinalTrain; }
+// The corresponding reader (RPCDeserializeAuto, SyncRunningMetroInfos) reads the items through
+// Base.ReadComplex, so this contract must stay complex (no Inline => TypeMark 0xFF per item).
+// MetroClientInfo only carries "which line + how long it has been running": the client derives the
+// carriage position and door/gate animation from the baked MetroPath of that line plus ElapsedTime.
