/* =========================================================================
   Tema Raudhah — aqiqah: taman dalam lengkung.

   Titik tolaknya lukisan cat air: lengkung islami bertepi sage, kisi emas,
   bulan sabit emas bergantung, bunga putih, dua anak domba di kaki lukisan.

   Gagasan utama: LENGKUNG. Lukisan dipasang sebagai latar tetap; sampul
   menaruh nama ananda di bidang kosong lengkung. Bentuk lengkung diulang di
   isi: kartu berpuncak lengkung berlis emas, foto ananda dalam bingkai
   lengkung, angka hitung mundur di dalam lengkung kecil. Bulan sabit dari
   lukisan dipakai ulang sebagai penanda judul.
   Warna: sage (utama), emas, gading, teks hijau tua.
   Huruf: Allura (nama), Gilda Display (judul), Mulish (teks).
