/* Mobile dropdown - same as desktop but hidden by default, we'll use JS or keep same? We'll keep same for simplicity, but mobile menu is separate.
   We'll handle mobile menu separately: we can duplicate the dropdown in mobile menu and hide/show via JS.
   For now, we'll just add the same dropdown to mobile menu and rely on the same hover? Not ideal.
   Better to make it click-to-toggle on mobile. We'll add a simple JS later.
   For now, we'll leave as hover which works on touch? Not great.
   We'll add a simple toggle via adding a class on click for mobile.

   We'll add a script later to handle mobile dropdown toggle.

   For now, we'll add the dropdown to both menus and later add JS to make it work on mobile.
