   A SEPARATE mobile app surface (#m-app), parallel to the

   so it can NEVER leak into the desktop layout, and the desktop
   DOM is never styled from this file. The only cross-cutting
   rules are the visibility swap at the 768px breakpoint.

   > 768px : desktop #app shows as-is, #m-app hidden.
   <=768px : #app hidden, #m-app shown (the native shell).
