/* ================================================= */

/*
1. SIDEBAR STATES:
   - Default: 230px width, full text visible
   - Desktop collapsed: 80px width, icon-only mode
   - Mobile: Hidden off-screen, appears as overlay

2. CLASSES REQUIRED:
   - .sidebar.hide - untuk mode collapsed
   - main.sidebar-collapsed - untuk adjust konten utama
   - .logo-icon - elemen ikon logo untuk mode collapsed
   - .active - untuk menu item aktif (ditambahkan via JS/PHP)

3. RESPONSIVE BEHAVIOR:
   - Desktop: Sidebar bisa di-toggle antara expanded/collapsed
   - Mobile (<768px): Sidebar menjadi overlay, konten utama full-width
   - Pastikan ada script toggle untuk menambahkan/remove class .hide

4. VARIABLES DEPENDENCIES:
   - --sidebar-bg, --sidebar-border, --sidebar-item - dari :root
   - --primary, --danger - untuk warna aktif dan logout

5. PERFORMANCE NOTES:
   - backdrop-filter pada sidebar mungkin tidak support di semua browser
   - Animated underline (::after) dimatikan di mobile untuk performa
   - Transition menggunakan cubic-bezier untuk animasi yang smooth
