   NAV KACA (liquid glass) — dipakai dashboard.html, admin.html, dan index.html (token + tombol tema).
   Diadaptasi dari referensi/nav-jagaabsen.html: HANYA tampilan & animasi.
   Isi menu, onclick, dan showTab() tetap milik masing-masing halaman.

   HP (< 768px)       : bottom-nav kaca + tombol tema bulat; mengecil saat scroll ke bawah.
   Tablet (768–1023)  : pil kaca di atas (isi = bottom-nav + tombol tema); sidebar tetap laci (☰ / Menu).
   Laptop (>= 1024px) : sidebar kaca mengambang di kiri, lensa bergerak vertikal, tombol tema di bawahnya.
   Tema tetap dari theme.js (<html data-theme>, localStorage 'na-theme').
