  "description": "Tracked new-build supply grouped by the BTS/MRT/SRT line serving each project's nearest station: project count, districts touched, property mix and median entry price. Line attribution comes from the developer's own copy, the OpenStreetMap line relation cited by the project record, or the operating network — never inferred from distance. A project beside an interchange counts on both of its lines, so the project column sums to more than the tracked total.",
