/* ═══════════════════════════════════════════════════════════════════════════
   blog.css — article typography for blog/ (built by tools/build_blog.py).

   Blog pages wear outline.css first, which gives them the topnav, the brand
   mark, the page shell and dark mode (the html:not([data-theme="light"])
   filter at the bottom of that file). This adds only what an article needs
   that an outline does not: a measured column, prose headings, lists without
   the outline's dot rows, code blocks, and the post list on the index.
