/* ===========================================================================
   The devices' help pages — /help/*.html

   Read inside the app's help window (a frame) or in a tab of their own, in
   the app's palette: the dark ground, the lavender of the controls, Inter.
   A page is a title, a lead, then sections — each a heading, prose, a
   screenshot of the device where one helps, and tables for the knobs.
