   blog.css — editorial / article layout for /blog
   ────────────────────────────────────────────────────────────────
   A reading-optimized single column on the brand tokens (styles.css).
   The product pages use the wide line-divided grid (seo.css); the blog
   is the opposite: a narrow prose measure for guides + comparisons.

   Reuses from seo.css: .breadcrumb, .compare (tables), .faq (FAQ).
   So a blog post links styles.css + seo.css + blog.css.

   TYPOGRAPHY RULES (same as the rest of the site): IBM Plex Mono only
   for CTA buttons + numbers; Instrument Sans everywhere else, sentence
   case (never all-caps); no em dashes in copy.
