/* ============================================================
   site.css — CSS BERSAMA TUNGGAL halaldoabangsa.id (TAHAP 8)
   Menggantikan site-modern.css + site-klasik.css (2 generasi
   desain yang terdrift sejak Tahap 5).
   DESAIN YANG MENANG: generasi MODERN (index/layanan/profil) —
   container 1280px, section padding 100px, tombol gradient,
   header gradient, nav hover background, radius 16/24.
   Selector khas klasik yang tetap dipertahankan (dipakai 7
   halaman lain + sebagian layanan): .dropdown, .reveal, .sr-only,
   .scroll-top-btn, .scroll-to-top, footer detail lengkap.
   PENTING: jika mengubah isi file ini, ganti ?v= di 10 HTML
   (saat ini ?v=3) agar cache pengunjung lama tidak basi.
