/* ===========================================================
   Dekan Cup Catur — Fakultas Teknik Universitas Tanjungpura
   Tema "Bagan Turnamen" — dirancang seperti papan pengumuman
   resmi turnamen catur yang dipasang di atas kertas gambar
   teknik (blueprint): kop surat berlapis lambang, notasi hasil
   ditampilkan sebagai cap tinta bernotasi asli (1-0, ½-½, 0-1),
   dan papan klasemen berupa cross-table dengan lempeng kuningan
   untuk tiga besar.
