   IDE — slice C shell
   --------------------------------------------------------------------------
   Three-region layout inside the existing topbar: sidebar on the left, the
   CodeMirror editor in the centre, and a thin status bar at the bottom.
   All colours come from the theme variables in base.css so the shell
   matches whatever theme the user has active.
