/* ============================================================

   🎓 LESSON: @media queries apply styles ONLY when the screen
   matches a condition. The most common condition is max-width:
   
       @media (max-width: 768px) { ... }
   
   This means: "IF screen width is 768px or less, use these styles"
   
   We have 3 breakpoints (sizes where layout changes):
   - Tablet  : max-width 900px
   - Phone   : max-width 600px
   - Sm Phone: max-width 400px
