/* Karangan — ucapan wisuda, lukisan cat air bergerak: halaman gedung kampus saat sore keemasan, jalan setapak
   berjajar papan bunga. Dibuka: papan bunga utama (papan.webp) naik dari bawah dan berdiri, tulisannya muncul
   baris demi baris seperti dirangkai (clip-path), topi toga dilempar ke udara, kelopak berguguran. Isinya: kartu
   ucapan, tangga perjalanan (list `journey`) yang naik ke anak tangga terakhir "hari ini", album, balasan.
   Tanpa JS adegan tidak dipakai dan semua isi langsung terbaca. */
