   APP — the studio chrome around the deck.

   Four zones, the arrangement that works for document editing: controls left,
   the live document centre, pages along the bottom, section progress right.
   The chrome is APEX-branded but deliberately quieter than the document, so
   the artwork is what your eye lands on.
