/* ============================================================
   K0G // article.css — styles the static /articles/ pages using the
   SAME theme tokens as the main app. styles.css (loaded first) defines
   the palette per theme and theme-init.js applies the visitor's chosen
   theme before paint, so articles match the rest of the site exactly
   (dark by default, and whatever theme/accent the visitor picked).
   Font is inherited from styles.css (JetBrains Mono).
