/* culvertvpn.com/blog — long-form layout on top of site.css.
   Same tokens, same two typefaces. The one deliberate difference from the landing page is
   the measure: posts are set at 66ch with a generous leading so a 1,000-word answer reads
   like an article, not a brochure. Hubs and the front page use one card style: title,
   description, date and reading time — nothing decorative. */
