     --motif-opacity : kekuatan motif di seluruh halaman.

                       diredam lagi oleh --veil-alpha di bawah, jadi
                       nilai ini mengatur motif di area kosong/pinggir.
     --motif-blur    : 0px = tajam, 1.5px = lembut kabur.
     --motif-size    : ukuran satu ubin motif. Makin kecil makin rapat.
     --veil-alpha    : kepekatan lapisan penenang di atas motif untuk
                       area yang berisi teks. Makin tinggi = teks makin
                       jelas, motif makin samar.

     SETELAN SAAT INI: LEMBUT (pilihan pemilik, 20 Sep 2026).
     Kalau ingin lebih kuat: opacity -> 0.70, veil -> 0.70.
     Batas aman paling kuat: opacity 1, veil 0.50 (teks mulai sulit). */
