/* =====================================================================
   APS ENTERPRISE — SISTEM VISUAL "STEEL & SIGNAL"
   ---------------------------------------------------------------------
   Prinsip:
   1. Warna sinyal (hijau/kuning/merah/ungu) HANYA dipakai untuk status
      mesin dan produksi, mengikuti konvensi andon di lantai produksi.
      Warna tersebut tidak pernah dipakai sebagai dekorasi.
   2. Warna aksi/interaksi memakai teal industri, hue yang tidak ada di
      palet sinyal, agar tombol tidak pernah tertukar dengan status.
   3. Angka, kode part, dan waktu memakai huruf monospace agar sejajar
      dan mudah dibandingkan pada tabel padat.
