/* =========================================================================
   Tema Kautsar — khitan: bingkai bulat emas berhias melati.

   Titik tolaknya video 3D lembut: dinding krem dengan bingkai bulat bercincin
   emas & ranting melati, balon sage-emas-putih berpita, masjid berkubah
   hijau, anak berpeci & berbaju koko sage.

   Gagasan utama: LINGKARAN. Nama di dalam bingkai bulat video; tiap judul
   diberi medali bulat bercincin emas berisi ranting melati yang menempel di
   tepi atas kartu; foto ananda & hitung mundur dalam lingkaran bercincin
   emas; ranting melati di sudut foto seperti di bingkai video.
   Warna: sage (utama), emas, krem, putih melati.
   Huruf: DM Serif Display (nama & judul), Jost (teks).
