//--- Built on the standard MQL5 Controls library (CAppDialog/CButton). Per the library's own source
//--- (Controls\Wnd.mqh CWnd::OnEvent, Controls\Dialog.mqh CAppDialog::ChartEvent), every control in
//--- this framework - including the dialog's own caption drag and close/minimize buttons - detects
//--- clicks exclusively through CHARTEVENT_MOUSE_MOVE hit-testing, which raises an internal
//--- EventChartCustom(CONTROLS_SELF_MESSAGE, ON_CLICK, control.Id(), ...) event; CAppDialog::ChartEvent()
//--- explicitly ignores CHARTEVENT_OBJECT_CLICK outright ("we are working with the CHARTEVENT_MOUSE_MOVE
//--- events"). So button clicks are wired the same way CDialog wires its own Close button - an
//--- EVENT_MAP/ON_EVENT(ON_CLICK, control, handler) entry - not by matching object names against
//--- CHARTEVENT_OBJECT_CLICK's sparam in the EA's OnChartEvent().
