   komponen kartu info, tabel kosakata, tombol interaktif, dan hasil
   kuis -- menyebabkan "kotak putih" yang tidak konsisten muncul di
   tengah tampilan dark mode, meski kontras teks/border tetap terbaca.
   Diperbaiki dengan override khusus dark mode yang menyesuaikan latar
   ke variabel gelap, MEMPERTAHANKAN makna warna asli (hijau=benar,
   merah=salah/bahaya, kuning=peringatan, ungu=aksen netral) dengan
   opacity rendah agar tetap kontras di atas latar gelap. */
