/* =========================================================================
   Tema Hikayat — buku dongeng pernikahan.

   Titik tolaknya video pembuka: buku bersampul linen berlis emas terbuka,
   lengkung-lengkung bermawar muncul dari halamannya (pop-up), kamera
   menyusuri lorong lengkung menuju papan berbingkai filigri emas.

   Gagasan utama: HALAMAN BUKU. Isi = halaman krem bersudut filigri emas
   (bingkai papan di video) dengan bayang lipatan halaman di tengah; buku
   terbuka bergaris emas di atas tiap judul.
   Warna: mawar pudar (utama), emas filigri, krem halaman, hijau daun.
   Huruf: Great Vibes (nama & judul), EB Garamond (sub judul), Lato (teks).
