    // The headless authoritative NETWORK battle mgr — the emitting twin of HeadlessBattleMgr. Emission
    // lives on the NetworkBattleSender, and the *override that actually invokes it* (SendPlayCard ->
    // NetworkSender.SendPlayCard) lives on NetworkStandardBattleMgr, NOT NetworkBattleManagerBase: the
    // base SendPlayCard is an empty virtual no-op (NetworkBattleManagerBase.cs:598). NetworkStandardBattleMgr
    // is the production standard-PvP mgr; its ctor also creates the NetworkSender (NetworkStandardBattleMgr.cs:92),
    // so no manual sender wiring is needed here. Extending the base instead would resolve state but never
    // emit (spec §7 risk 2a). RNG overrides are identical to HeadlessBattleMgr (the same BattleManagerBase
    // virtuals + RandomSourceBridge), so the M14 rand-list emit reuses this mgr unchanged. M13's
    // deterministic card never exercises a roll.
