   MalerPind – prisberegner (stand-alone page)

   Part 1 repeats the few base rules this page needs from the website's
   static-site/static/css/style.css, so the calculator can run on its own.
   Drop part 1 when the calculator moves into the site – the tokens and class
   names are the same. Part 2 is the calculator itself (everything .calc*).
