   MARKDOWN — rendered content bodies
   Styles the output of Rubycities::MarkdownRenderer. Wrap that output in
   `.markdown-body` (the rubycities_markdown helper does).

   CSS resets flatten the tags this HTML is made of — headings lose their
   size, lists their markers — so both are restored here, not merely tweaked.

   Every colour is a custom property with a fallback. Signalbox defines the
   --rc-* tokens; a public theme may define them too, or link this file as it
   is and take the fallbacks:
     <%= stylesheet_link_tag "rubycities/markdown" %>

   compound values. Only the common scopes are mapped — anything unmapped
