/* ============================================================================
   Advertisement banner carousel (home page).
   Fully namespaced: every rule is scoped under .adv-carousel-section, custom
   properties are on the wrapper (not :root) and prefixed --adv-*, and every
   class is prefixed .adv-* so nothing collides with Bootstrap or the site theme.

   NOTE: the site uses html{font-size:62.5%} (1rem = 10px). The reference design
   assumed 1rem = 16px, so this component uses PX units throughout to stay the
   intended size regardless of the site's root font-size. The section heading
   deliberately reuses the theme's .section-title markup so it matches the site.
