"""Custom authoritative server (ans4) for the dnssec_py suite.

Per-domain response handlers live one-per-module in sibling *_ans.py files
(e.g. rrsig_labels_signer_ans.py); this loader installs each into a single
AsyncDnsServer.  Keeping each domain's crafted-response logic in its own
file bounds its scope as the server accrues unrelated domains.
