/* -----------------------------------------------------------------------------
   Rendered markdown content.

   Everything here is scoped to `.markdown-body`, the wrapper every page puts
   around output from MarkdownProcessor - the markdown viewer, and the About
   section of a course or module. It lives apart from markdown-viewer.css because
   that file also restyles global `.btn` and `.badge`, which no page outside the
   viewer can afford to load.

   Add the class and this stylesheet together: the class alone is unstyled, and
   the stylesheet alone matches nothing.
