   REDESIGN — BYRA Cloud. Tema: MODERN CYBER CLOUD (bersih).
   Revisi:
     1. Grid kotak-kotak DIHAPUS (kesan cyber cukup dari gradient + glow).
     2. Skala dinaikkan supaya pas di layar desktop 100% (tidak kekecilan).
     3. Ikon tombol tema diperbaiki -> selalu SATU ikon bersih:
        matahari (light) / bulan (dark), tidak lagi dobel.
   Semua nama class/selector LAMA dipertahankan agar HTML tetap jalan.
   Font: Manrope (satu keluarga, konsisten).
