/*
  Designed articles (Pages/Blog/Designed/*.cshtml).
  Loaded only when an article's body is a {{designed:name}} marker.

  Matches regular blog articles (.container.blog-article + .blog-body):
  same 900px centered column, same site fonts (site.css), same body size and colors.
  Every selector is scoped under .designed-article and every class is prefixed da-,
  so nothing here reaches the rest of the site and site classes can't reach these components.
