/* assets/css/admin.css - tema visual panel admin/klien/staff (di atas Bootstrap 5).
   Dipakai BARENG oleh admin/includes/header.php & client/includes/header.php - jadi perubahan di
   sini otomatis berlaku utk ketiga peran (admin/klien/staff) di seluruh halaman panel, TANPA
   menyentuh halaman publik undangan (yang pakai CSS tema masing-masing, bukan file ini).
   Pendekatan: styling lewat ID unik yang sudah ada (#tabMenu, #tabMenuContent) & kombinasi class
   Bootstrap yang spesifik (mis. stat card), supaya tidak perlu mengubah struktur HTML di
   admin/invitation_detail.php sama sekali - jadi aman dari risiko merusak logic yang sudah ada. */
