"""A web form's phone field carries `flexible_phone_validator`, on both targets.

`_field_for` gave a phone row a bare CharField, so any 25 characters a stranger
typed reached `Lead.phone` or the auto-created `Contact.phone`. Both columns
declare the validator, but only `full_clean` runs it and the create paths do
not call that, so the form serializer is the one place it can be enforced.
