Regression from the partial-order board: _job_presences emitted a card for any area containing a `ready` step. These recipes seed ALL downstream steps to `ready` at job creation, so a job showed in every future stage at once (e.g. WO-30061 across racking/receiving/plating/inspection) even though no parts had advanced there. Fix: a stage shows ONLY where parts physically are (qty_at_step > 0, which includes the first-active seed) OR where a step is in_progress/ paused. A merely ready/pending future step with no parts no longer shows. Strict sequential progress falls out for free — the qty_at_step seed sits on the lowest-sequence non-terminal step and advances as each completes.
