/* =========================================================================
   Tema Nabastala — aqiqah di langit: awan, bulan sabit & bintang emas.

   Titik tolaknya video cat air: langit biru muda berawan putih, bulan sabit
   & bintang emas bergantung pada benang, kilau bintang kecil, dua anak
   kambing duduk di atas awan.

   Gagasan utama: AWAN. Kartu isi bertepi atas bergelembung seperti awan
   (mask lingkaran beragam ukuran); bintang emas bergantung di atas tiap
   judul; hitung mundur dalam gelembung awan; foto ananda dikelilingi
   bintang kecil.
   Warna: biru langit (utama), emas, putih awan, teks biru tua.
   Huruf: Cormorant Infant (nama & judul), Quicksand (teks).
