   yai-mobile.css
   Global responsive fixes for YAI on phone (<768px) + tablet (768-991px).
   Loaded as the LAST stylesheet so it can override component-level rules.

   Breakpoint policy:
     - sm  : 576px  (large phones, landscape)
     - md  : 768px  (tablet portrait)         <- nav switches to desktop here
     - lg  : 992px  (tablet landscape)
     - xl  : 1200px (desktop)
