    // POST-TASK-8 (multi-instancing migration): now empty. The historical hygiene gap this class
    // closed (HeadlessEngineEnv.NewNetworkEmitBattle leaving IsForecast=false + a stray injected
    // agent visible to a later solo fixture) was a PROCESS-GLOBAL leak via the now-deleted
    // BattleManagerBase._isForecastFallback + ToolboxGame._realTimeNetworkAgentFallback statics.
    // Both fields are gone: IsForecast/RealTimeNetworkAgent live on the per-test ambient context
    // (TestBattleScope's BattleAmbientContext), so scope Dispose drops them. A later fixture's
    // new TestBattleScope starts a fresh ctx with IsForecast=true and a null NetworkAgent by
    // default — exactly the EnsureInitialized invariant the old TearDown manually restored.
    //
    // Kept as a marker base class so derived fixtures don't churn; can be deleted in Task 9.
