   PREMIUM DESIGN LAYER — SSS College for Women, Arni
   Loaded after style.css. Elevates typography, palette depth,
   and motion without touching the existing markup structure.

   Signature element: "The Gilded Insignia Rule" — an animated
   gold seal-line that draws in under every section title and
   frames achievement moments, echoing a certificate/graduation
   ribbon — the visual thread of an institution built on results.
