/* Native app: the app draws its own bottom chrome (tab bar) over the web view, so the floating
   back-to-top button has to sit above it instead of underneath, where it cannot be tapped.
   .nd-native-app is set on <body> by new-design-master-layout.blade.php (this page extends it) -
   server-side for the new app, plus a UA check there for the old one, whose plain-string
   User-Agent isNativeApp() cannot read.

   Specificity 0,2,0 against the base rule and the <=600px override above (both 0,1,0), so it wins
   at every width without !important and without a media query of its own. On the web both of those
   keep applying unchanged - this rule only ever matches inside the app. */
