/**
 * A client account coming into existence without a staff member creating
 * it by hand.
 *
 * Two entry points now reach this — the public registration form and a
 * first successful LDAP sign-in — and they must agree on the parts that
 * are policy rather than presentation: whether the account is active or
 * waits for approval, which group it joins, and who gets told. Keeping one
 * definition is the same reasoning FileSharing and StoreUploadedFile
 * already follow.
 *
 * What stays with each caller is what genuinely differs: the registration
 * form's custom fields and group requests, and LDAP's directory stamp.
