/* ============================================================================
   Pipeline — layout
   Kanban stage board for work orders: In preparation · In engineering ·
   In production · Completed. Brand-restrained — the columns are NEUTRAL; the
   only colour on the board is delivery-urgency (the due chip + an at-risk left
   edge), because colour is feedback, never decoration. Layout only; all
   colour/space/type from --sds-* tokens. Shared chrome (review-bar, .num,
   .muted) lives in ../_shared/base.css.
