/* ==========================================================
   Undangan Live — RSVP & buku ucapan ([inv_rsvp])
   Kartu undangan cetak sebagai acuan: krem hangat solid,
   garis tipis emas pudar, tipografi serif untuk judul & angka,
   field bergaya garis-bawah. Satu ornamen di atas jadi elemen
   yang paling "berani"; sisanya sengaja dibuat tenang.
