    | Geocoding

    | `longitude` from the postal fields using a public geocoder. By default
    | this uses Nominatim (OpenStreetMap) — free, no API key, requires a
    | descriptive User-Agent and a hard limit of one request per second
    | (operations.osmfoundation.org/policies/nominatim/).
    |
    | The observer holds a Laravel `Cache::lock` while it makes the call, so
    | even when the same code is running in multiple workers only ONE call
    | hits the upstream at a time, and the 1-req/sec floor is enforced
    | globally across the cluster via a shared cache timestamp.
    |
    | Set `enabled => false` to turn the observer off (e.g. in CI). Set
    | `update_only_when_missing => true` to keep manually-entered coordinates
    | and only geocode rows whose coordinates are still null.
