/* Shared phone behaviour for the CW apps.

   The apps are built for a desktop console layout. Rather than reflowing them
   for phones, sections that are secondary on a small screen can be folded away:
   a `.mobile-fold-toggle` button is placed in front of a run of sibling
   elements carrying `data-fold-item="<group>"`, and shared/mobile.js hides that
   run on phones until the operator taps the toggle.

   No wrapper element is introduced, and above the breakpoint the toggle is
   display:none and no element carries a fold attribute — so the desktop layout
   is exactly the markup as it was before folding existed. The breakpoint is the
   640px the apps already use for their stacked layout. */
