/* ══════════════════════════════════════════════════════════════════════════
   Blog — /blog and /blog/<slug>

   Loaded after styles.css and built only from its tokens, so the articles
   read as the same site as the landing.

   Desktop gets the landing's full 1180px stage: a wide hero, then the
   article beside a sticky table of contents. The text column itself stays
   near 70 characters — wider lines are harder to read, not easier — so the
   extra room goes to the hero and the contents rail, not to the paragraphs.
