   TEMA 18 — SINEMA (PREMIUM)
   Layout sinematik, bukan sekadar ganti palet: adegan full-screen,
   letterbox, foto Ken Burns, grain film, kartu bab, dan hitung
   mundur gaya bioskop. Semua aturan hanya aktif saat
   <html data-tema="tema-18">, jadi 17 tema lain tidak berubah.
   Gerak memakai transform/opacity saja (ringan di HP) dan mati
   kalau pengguna mengaktifkan prefers-reduced-motion.
