/* Blog layout, shared by the index and every article.
   Articles migrated from the old per-article templates still carry their own
   <style> block inside the body, which lands after this file and therefore
   keeps winning — their appearance does not change. Once an article is
   rewritten as markdown and that block goes, this is what styles it. */
