            The neighborhood/ward names and coordinates customers' delivery-location search matches against.
            Correct a coordinate here if a pin lands in the wrong place, or add a new area directly.
            Areas the AI resolves from a customer's search (because no coordinate was on file yet) are added
            here automatically, tagged <strong>ai</strong>, so the same place never has to be re-guessed.
            {% if unresolved_count %}<strong>{{ unresolved_count }} area{{ unresolved_count|pluralize }}</strong>
            still {{ unresolved_count|pluralize:"has,have" }} no coordinates — a customer searching one of those
            will trigger an AI lookup.{% endif %}
