/* ==========================================================================
   Binarymission documentation - code windows (pairs with code-window.js)
   ==========================================================================
   Surfaces and chrome come from the --cw-* properties below. Their defaults
   read the binarymission.co.uk theme tokens (site-shell.css); a site whose
   content uses other tokens re-points them on `.cw` in its own stylesheet.
   The syntax palette has a light and a dark set, picked per window by the
   script from the window's text colour; keywords and tags are mixed from the
   theme's accent so each palette carries the theme's own colour.
