    // ============================================================
    // IDashboardHubNotifier — abstraction over DashboardHub SignalR push.
    //
    // Concrete implementation (DashboardHubNotifier) lives in FrameworkSL, wrapping
    // IHubContext<DashboardHub, IDashboardClient>. Keeps FrameworkBLL free of ASP.NET/SignalR
    // assembly types — same pattern as ISysJobHubNotifier/SysJobHubNotifier.
    //
    // This only helps a BLL class running IN FrameworkSL's own process. A BLL class in a
    // different host (Accounts/Analytics/Compliance, each its own process) cannot reach
    // DashboardHub via DI at all — no shared container, same class of constraint documented for
    // ISysJobHubNotifier's own NoOp fallback on other hosts. Those hosts must call the new
    // POST /Dashboard/NotifyDataChanged endpoint over HTTP instead (see FrameworkSL's
    // Endpoints/Dashboard/NotifyDataChanged.cs) — not implemented as an internal HttpClient bridge
    // yet, flagged as the concrete next step once a real trigger (e.g. Compliance's
    // AlertCheckSubscriber) is wired to call it.
    //
    // Registration in FrameworkSL Program.cs:
    //   services.AddSingleton<IDashboardHubNotifier, DashboardHubNotifier>();
    // ============================================================
