/* =========================================================
   pages.css — layout for standalone subpages
   (course, about, enroll, blog, blog posts)

   The homepage uses .snap-section (height:100vh) plus .fade-up
   (opacity:0 until .is-visible is applied by the scroll observer).
   Subpages are long-form documents, so they use their own
   scrolling layout and never depend on those classes.
