/* ============================================================
   IBS HIDAYATULLAH — DESIGN SYSTEM BERSAMA
   Dipasang di SEMUA modul (Portal, Absensi, Tahfizh, Admin,
   Absensi Ustadz, Registrasi) supaya tampilan konsisten &
   terasa seperti satu aplikasi modern, tanpa mengubah struktur
   HTML atau logika JS yang sudah ada — murni lapisan polesan
   visual (typography, shadow, animasi, micro-interaction).
