   Fixed chrome geometry

   The title bar's height anchors everything pinned below it: the navigation
   strip, the mobile menu panel, and the body's top padding. Holding it in one
   custom property is what keeps the mobile menu welded to the bar -- the bar
   grows to 80px between 576px and 768px, and the menu used to stay pinned at
   a hard-coded 70px, so it opened 10px underneath the bar.
