  Features tagged telecom=data_center or building=data_center (nodes, ways, relations; `out center tags;`), queried
  per world tile (13 non-overlapping bboxes), sequential, ≥ 10 s apart, resumable cursor in connector state.
  robots.txt of overpass-api.de disallows /api/ for generic crawlers; the Overpass API is a query service whose
  usage terms are the Overpass "Commons" guidance (https://dev.overpass-api.de/overpass-doc/en/preface/commons.html:
  ≤ ~10 000 requests and ≤ ~1 GB per user per day) — we send ~13 requests / ≈ 3 MB per full pass, so respectRobots is
  deliberately false for this API endpoint (see docs/connectors/osm-overpass.md).
