/* ============================================================
   MOBILE.CSS - Responsive styles for My Budget App
   ============================================================

   This file ONLY contains media queries for small screens.
   It does NOT modify anything on desktop/laptop.

   !important is used where style.css rules need to be overridden.

   BREAKPOINTS:
   - 768px = Tablets (iPad portrait)
   - 480px = Phones (iPhone)

   To disable all mobile styles, remove the <link> to mobile.css
   from index.html and everything reverts to the desktop layout.
