/* ==========================================================================
   Rich content — shared styling for everything RichContent renders.

   One stylesheet for forum posts, feed posts, comments, profile bios and the
   editor's preview pane, so a post looks the same everywhere it appears.
   All class names are prefixed rc- and are emitted only by the server-side
   renderer; user content can never produce one, because the renderer strips
   class attributes from anything it did not build itself.
