/* Mobile CTA in menu is handled by duplicating the button or JS moving it. 
   For this implementation, assuming structure: 
   .nav-cta is OUTSIDE ul in HTML, so we hide it on default mobile/desktop split 
   and show it inside menu if moved, OR style it specifically.
   Actually, common pattern: Hide independent CTA on mobile, duplicate inside menu.
   OR: Use the one in header if space permits (usually doesn't).
   
   Let's assume the button is IN structure like:
   NAV > CONTAINER > LOGO, HAMBURGER, UL, BTN
   On Mobile: UL is hidden drawer. BTN is hidden or moved.
   
   We will hide the desktop .nav-cta on mobile.
*/

/* Wait, if logic is "inside menu", we need it there. 
   If it's outside UL in HTML, we can't easily put it inside without JS.
   We'll assume JS moves it or usage of a mobile-only button inside UL. 
   Existing HTML had it Outside. We'll use media queries to show/hide.
