   TrueCoat "Paint the page" — experimental colour theme picker
   Pairs with assets/js/theme.js.

   TO REMOVE: delete this file, assets/js/theme.js, and the two tags
   marked THEME-PICKER in the <head> of index.html.

   Sections 2 and 3 only apply while <html data-theme="..."> is set, so the
   default (Classic) look is untouched by this file.
