/* ==========================================================================
   Article pages — long-form typography.
   Loads on top of /static/site.css, which supplies the tokens, nav, and
   footer. This file styles the reading column only.

   Legacy class names (.bodyText, .subTitle, .listItems, .codeblock) are kept
   deliberately: the prose markup in each article is unchanged, so restyling
   happens here rather than in six HTML files.
