# /fp/jobs/plant_overview — JSON endpoints powering the native-job
# Plant Overview kanban (operator triage view, Phase 6 of the native
# job migration). Columns are fp.work.centre rows; cards are
# fp.job.step rows in ready / in_progress / paused state. Drag a
# card across columns to reassign that step's work_centre_id.
