   Prime Marketing — Blog styles (additive).
   Loaded via base.njk {{ extraStylesheet }} on /blog/, posts,
   category pages, and the author page. Reuses global tokens and
   global classes (.container, .eyebrow, .btn, .h-2, .em-italic,
   .reveal, .grain, .final-cta, .faq-item) from styles.css; this
   file styles everything blog-specific plus a few editorial
   patterns (.premise, .about-pullquote, .compounds-link, .crumb)
   that the original pages define inline rather than globally.
