       For this complexity, let's keep it simple: 
       On mobile, just showing the Level 2 links (Sidebar items) is often enough. 
       If we want to show Level 3, it becomes a 3-level accordion. 
       Let's stick to showing Level 2 links as the final destination for mobile to save space, 
       OR make the sidebar items just links. 
       
       Current code: Sidebar items are <a> links. So they work.
       We will HIDE the .mega-content on mobile to avoid deep nesting complexity for now.
