Account creation moved to admin, which owns accounts, and the marketing
form now posts there. sitesvc keeps the contact mailer only.
DEPLOY LAST: sitesvc's verify endpoint must stay live until every
outstanding pending signup has expired, or an in-flight verification link
breaks. Do not roll this out until the site change has been live 24 hours
and site_pending_signups is empty.

The signup form's JSON field becomes instance_name, and the pending-signup
document field with it. That collection is sitesvc-private and expires after
24 hours, so no migration is needed, but in-flight signups written before the
deploy will fail verification.
