/* Ruang Riset — sistem tampilan, versi modern.

   Palet tetap berakar pada warna Melayu Riau: hijau daun dan laut, kuning
   keemasan sebagai tanda kebesaran. Yang berubah adalah cara memakainya:
   gradasi lembut menggantikan bidang datar, sudut dibulatkan, dan bayangan
   tipis dipakai untuk memberi kedalaman. Tabel angka sengaja dibiarkan tegas
   supaya tetap mudah dibaca. */
