/* tpl-kanon.css — LAPISAN 3 ("kanon").
   Karakter: majalah pernikahan. Ruang kosong lapang, sudut tajam (radius 2px),
   garis rambut sebagai pemisah, section BERNOMOR besar. Tanpa bayangan sama
   sekali — kedalaman dibangun dari garis dan jarak, bukan dari drop shadow.

   Prinsip yang dijaga:
   - Nomor section besar tapi `aria-hidden` (di markup), jadi pembaca layar
     tidak mendengar angka tanpa arti.
   - Judul memakai huruf serif lebar; nama mempelai jadi pusat perhatian.
   - Tata letak desktop benar-benar berbeda: dua kolom untuk mempelai. */
