Resume-on-load (S-26) restores any open registration for the logged-in bsn, so on the
shared verify stack the specs can no longer share jan-burger: verify-domain submits as
jan-burger (123456782) before the e2e, and that open registration was being resumed on
login. Each self-service spec now uses its own citizen — registration→emma-burger,
resume→sanne-burger, withdrawal→lars-burger — none touched by the verify-* checks or
each other. jan-burger stays the documented citizen for the API-level verify checks.
