+ * Notes from probing the runtime:
+ *  - Zone IDs come back as `/hostedzone/Z…`; the bare ID is accepted everywhere, so
+ *    resources are keyed by it.
+ *  - A new zone holds the apex NS and SOA records, and `DeleteHostedZone` refuses
+ *    with `HostedZoneNotEmpty` (400) while any other record remains, as on AWS.
+ *  - A missing zone is `NoSuchHostedZone` with HTTP 404.
+ *  - The runtime stores record values without checking them (an A record of
+ *    `not-an-ip`, unquoted TXT text), so the AWS rules are applied here.
+ *
+ * Records are the zone's child items, keyed by name, type and set identifier,
+ * which is what makes a record set unique in Route 53.
