   Container width fix (applies at ALL screen sizes)

   width (from conftool.inc.php's $ctconf['totalwidth']) via an
   inline <style> block. On any window narrower than 900px this
   forces horizontal overflow — the header (widest element) was
   spilling off the right edge with a scrollbar. Making the
   container fluid up to that same 900px cap fixes it everywhere,
   not just below a mobile breakpoint.
