/* ============================================================
   KDS BOARD — papan dapur hidup (diambil dari referensi, diperbaiki)
   Kanban 3 kolom: Masuk -> Dimasak -> Siap.
   Perbaikan atas referensi:
   - kolom kosong punya empty-state (bukan terbaca seperti bug)
   - bar progres diberi label waktu, bukan angka tanpa arti
   - label kolom punya kontras cukup
   - tanpa border-left berwarna (dilarang craft-floor); status lewat
     latar kartu + label + bar
