"""Domain entity: PersonalData (parent profile).

A PersonalData represents a parent in the planning workspace. It intentionally
exists without a User login so that solo planning for a partner who hasn't
registered is possible (see ARCHITECTURE.md §3.0).

personnummer storage is discouraged (see §11). If kept, personnummer_enc must
be keyed HMAC / authenticated encryption — never a plain SHA-256.
