/* ---------------------------------------------------------------------------
   Interview frame height
   ---------------------------------------------------------------------------
   Enketo scrolls internally, so a short frame produces two nested scrollbars
   and a question list the interviewer has to hunt through an item at a time.
   Taller on a phone, where the frame is the whole screen, than on a desktop
   where the respondent panel sits alongside it.

   dvh rather than vh: on mobile Safari and Chrome the address bar collapses on
   scroll, and 100vh refers to the LARGER viewport — so a vh-sized frame is cut
   off by the browser chrome until the user scrolls. dvh tracks the actual
   visible height. The vh line before it is the fallback for older WebViews.
