/* =========================================================
   MOBILE / TABLET RESPONSIVE LAYOUT
   These rules change the desktop layout for smaller screens.

   1100px:
   - collapses major 2-column sections into 1 column
   - turns off sticky side panels

   800px:
   - stacks top bar content
   - changes specifier sliders to a vertical layout
   - keeps tabs scrollable instead of cramped

   560px:
   - reduces padding
   - makes buttons full width
   - shrinks the live radar for phone screens

   If mobile looks broken later, check these three media queries first.
