   ║  This stylesheet AND its companion template                            ║
   ║  (archive-sfwd-courses.php) are the LIVE courses-catalogue gateway     ║
   ║  for the WordPress 101 product line. Christopher has reviewed the      ║
   ║  rendered output and signed off on it.                                 ║

   Loaded conditionally via inc/setup.php on
   `is_post_type_archive('sfwd-courses')`. Tokens + base are inherited
   through the main stylesheet (also enqueued). Built 2026-05-17 alongside
   archive-sfwd-courses.php as the bespoke courses-catalogue gateway,
   replacing the generic archive.php fallback that was rendering /courses/
   as a thin "ARCHIVE / Courses / Browse all / All items" page.

   Authored into the `page-types` layer to sit at the same cascade level
   as archive-service.css, archive-podcast.css, etc.

   BEM prefix: .course-archive__*  (parallel to .course-detail__* on the
   single-course surface, so the two related surfaces read as one product
   family in the stylesheet alphabetical listing).

/* ==========================================================================
   Un-layered section-rhythm + inset-card padding overrides

   `.site-shell` is declared un-layered in main.css with
   `margin: 0 auto; padding-inline: 1.125rem`. Cascade-layer rules —
   including everything inside `@layer page-types` above — always lose to
   un-layered rules of equal specificity, so the `margin-bottom` and
   `padding-inline` declarations on .course-archive__hero / __listing /
   __deflectors / __faq / __footer-cta inside the layer would be silently
   overridden by .site-shell's defaults on every section that shares both
   class hooks.

   The fix is to escape the layer for these two property buckets only.
   The rest of the file (colour, layout, padding-block, type) stays
   cleanly inside @layer page-types; only the bottom-margin tokens and
   the hero's inline padding leak out to compete on the same un-layered
   plane as `.site-shell`.

   Pattern matches single-course.css. See memory:
