/* ─────────────────────────────────────────────────────────────────
   blog.css — Blog article pages (post/<slug>.html) and the blog
   index (blog.html). Layout/nav/footer/closing CTA come from
   site.css + service-page.css; this file styles the article header,
   long-form body typography, and the index card grid.

   Adapted from the Pure Mold Masters reference implementation's
   blog.css — retuned to PAA's token names (--color-brand-primary-*,
   --radius-card / --radius-card-lg, --rgb-navy-deep shadows) so the
   blog reads as part of the same design system as the rest of the
   site rather than a bolted-on subsection.
