/* Blog articles: the information-page shell from legal.css, plus long-form reading styles.
   Loaded after legal.css on article pages and the 404 page only, so an article change can
   never alter a policy page. legal.css styles every header, nav, footer, section, button
   and input, so the article's own blocks use classes and undo those rules explicitly.
   body.post is the article layout: the city behind the title, a sticky bar, the text
   with a side column of contents, then rating, sharing, author and comments. */
