Default message: signup requires a business email address; personal / disposable providers are not accepted
HTTP status:400(client)
Problem. Signup was rejected by the business-email gate. Cause.
The supplied email is on a free-mail, disposable, or role-based
address list — see §1 of the onboarding redesign spec. The response
carries the matching reason under error.fields so the UI can
localise (values include freemail, disposable, role_based).
Fix. Sign up with a corporate email, or contact support if the
domain was flagged in error. HTTP 400.
