  "production_notes": "A later working-district cooperative presented freestanding on flat ground, it translates expensive civic recursion into repeatable steel roof bays and replaceable market carpentry.",
  "departure": "Its horizontally spreading serrated roof and light industrial assembly contrast with the residence’s stone clusters and the monument’s single cubic mass.",

    "Nested shopfront frames",
    "Rubble bases with lighter upper construction",
    "Clearly expressed structural bays"
