Type Alias StaticContentFactory 

pub type StaticContentFactory = Rc<dyn Fn(&TabHandle) -> Box<dyn Widget>>;

Closure that builds a static tab’s content widget. Called once per static tab — on the TabWidget’s first build that includes it. The resulting pane is then memoized: rebuilds caused by adjacent dynamic-model mutations reuse the same pane WidgetId, so internal state (focus, scroll, animation progress, …) survives.
