Pulling together a summer briefing on school-density disparities for children aged 8–14 across the 23 special wards. Out of `tokyo_places` I need every school relevant to that age range whose point sits inside the wards rectangle in `tokyo_23wards_bbox`. A colleague will visualise the result in R, so it has to land as `tokyo_schools.geojson`. Each feature's properties must use these exact keys: `id`, `name`, `confidence`, `address_freeform`, `address_locality`, and `address_postcode`.
