/* ======================================================================
   DIPLOMA PROGRAM SECTION — Khurana Tech Academy
   ----------------------------------------------------------------------
   NEW ADDITIVE STYLESHEET ONLY.
   • Every selector starts with .kta-diploma, so nothing here can leak
     into — or be affected by — existing sections.
   • Reuses the site's Bootstrap 5.3 grid, Rubik font and Font Awesome
     icons. No new dependencies. No JavaScript required.
   • Brand color is inherited via Bootstrap variables (--bs-primary)
     with safe fallbacks, so it matches your existing theme.
