    Interface WhiteboardWidgetSubmittingEventArgs

    BEFORE-event args for the board/host WidgetSubmitting output — raised after a widget's MJWhiteboard.submit payload passed validation (marker + tracked source + size cap) but BEFORE it is surfaced through WidgetSubmitted. Handlers run synchronously; set Cancel to true to drop the submission (no WidgetSubmitted fires and nothing reaches the agent/consumer).

    interface WhiteboardWidgetSubmittingEventArgs {
        Cancel: boolean;
        Event: WhiteboardWidgetSubmitEvent;
