/* ===========================================================================
   Dunaway Fleet - shared shell

   The layout rule that drives everything here: the page never scrolls. The
   header and the rail are fixed, and the content region owns its own scroll.
   Tables scroll inside their own pane with a sticky head. That is the fix for
   the sizing problems in the SharePoint build, where six screens shared one
   scroll container and one fixed 1200px column.
