/* ============================================================================
   Page frame: topbar, two-column shell, footer, and the responsive collapse.

   The shell is a fixed-width rail plus a fluid content column. Below 900px the
   rail becomes a horizontal scroller so the hierarchy stays reachable on a
   phone without hiding it behind a toggle — with many keywords the rail is the
   primary navigation, so it must never disappear.
