 |  Sidebar navigasi bersama (halaman admin + halaman toko index.php;
 |  index.php memakai aset ini dengan markup menunya sendiri).
 |
 |  Sifat:
 |   - Desktop (>= 901px): sidebar menempel di kiri, konten
 |     digeser lewat `padding-left` pada <body class="nav-body">.
 |   - Mobile (<= 900px): sidebar jadi drawer tersembunyi,
 |     dibuka lewat tombol hamburger, ditutup dengan backdrop,
 |     tombol ✕, atau tombol Esc.
 |
 |  Semua warna memakai variabel tema yang sudah ada di
 |  admin.css / style.css. Untuk tema gradasi, `--warna-utama`
 |  berisi gradient sedangkan `--warna-solid` warna ratanya,
 |  jadi --nv-solid selalu jatuh ke warna solid yang valid.
