The old domain's deep links 301 to the asurascans.com root, discarding the
path, so a page on it never yields a series document and a stored address on
it never yields a series page. #94 pinned each Site to one hostname, which
already rejects such an address server-side; this removes the remaining
references so nothing invites a Reader onto the dead host.
Live deploys still carry the origin in their own .env and must drop it there
too - the allowlist is read from the environment, not from these defaults.
