/* ===========================================================
   2IA06 — papan jadwal kuliah
   Konsep: papan keberangkatan (departure board). Jadwal kuliah
   pada dasarnya adalah tabel waktu, jadi tampilannya mengambil
   bentuk papan split-flap: dasar gelap, angka jam tegas dengan
   lebar tetap, satu warna aksen (kuning gading) untuk kelas yang
   sedang berjalan. Baris rapat bergaris tipis, bukan kartu bulat.
