/* ==========================================================================
   KCC Online Admission — applicant landing (campus.php)
   --------------------------------------------------------------------------
   Loaded ONLY by campus.php, so everything here is safe to scope loosely.

   Two constraints shaped this file:
   1. campus.php sends `Content-Security-Policy: default-src 'self'` — no
      external font hosts, no reliable inline <style>. Hence: system-serif
      display stack, and every rule lives here rather than in the page.
   2. `/img/` is excluded from the deploy, so no photographic hero is
      available. The background is built entirely from gradients + an inline
      SVG grain (allowed by `img-src 'self' data:`).
   ========================================================================== */

/* Navy and gold are sampled from the KCC emblem itself (img/sscLogo.png):
   #002060 and #F0E0A0 are its two dominant colours. The darker and lighter
   steps exist only to give the hero gradient depth. */
