     tried to lay the sidebar out as a horizontal strip, but only the sidebar's
     *direct* children (.brand/#nav-container/.sidebar-footer) are flex items —
     the actual nav links one level down stay a plain vertical block list. With
     the sidebar back in normal flow at width:100%, it and .main (flex:1) both
     fight for the same row and the sidebar's full-height nav column wins,
     which is the "nav takes over the whole screen, content unreachable" bug.
