   📱 BREAKPOINT REFERENCE

   Copy these when you need media queries:

   @media (min-width: 768px)  { }   // Tablet
   @media (min-width: 992px)  { }   // Desktop
   @media (min-width: 1200px) { }   // Large desktop

   ⚠️ Always use min-width (mobile-first)
   ⚠️ Never use 767px or 991px
      Use exactly 768px, 992px, 1200px - no other numbers
