   help.css — the help centre (help/ and fr/aide/)

   Loaded after pages.css, on the help pages only. The pages reuse the blog's
   title band (.blog-head), its listing ground (.blog-list) and its article
   frame (.article, .prose, .article__related); this file adds what a guide
   needs on top: a breadcrumb, a table of contents, code samples, parameter
   tables, and the guide cards of the index.
