/* Long-form reading pages (guides, blog, newsletter) — let the page scroll
   naturally. The promo banner pinned to the top and the sticky nav got in
   the way of long-form navigation, so we override both back to static. The
   `:has()` selector scopes this strictly to pages that mount `main.guide-wrap`,
   so the marketing site keeps its sticky banner everywhere else. */
