/* Rantang — ucapan terima kasih, lukisan cat air bergerak: meja jati beralas batik sogan di dekat jendela pagi,
   rantang enamel bermotif mawar di tengah (tiga susun + tutup dari satu gambar susun & satu gambar tutup, gagang
   SVG). Dibuka: gagang terangkat, tutup dibuka ke samping, susun atas & tengah turun ke kiri-kanan meja, harum &
   kelopak melati naik. Isinya per susun: surat, daftar "terima kasih untuk…" (list `reasons`), foto di piring enamel,
   lalu balasan ("kembalikan rantangnya"). Tanpa JS adegan tidak dipakai dan semua isi langsung terbaca. */
