/* ============================================================================
   surfaces-editorial.css
   Scoped redesign of the "Selected Surfaces" portfolio section on the homepage
   (public/index.php, inside black section data-id="a8ca749").

   Namespaced under .italica-surfaces so it cannot affect any other section,
   the other black section below it, the navbar or footer.

   Dark editorial gallery: large featured surface + meta + thumbnail rail,
   smooth crossfade, autoplay, arrows, progress. Brand blue #5394B3 accent.
   Fonts already loaded by the site: "DM Sans" + "Nunito Sans".
   Reveal uses AOS (already loaded + AOS.init() in footer); carousel has its
   own scoped JS (js/surfaces-carousel.js).
