/// 5. Cross-user access control

/// fresh, pre-verified Kratos account, logs in, and exposes `session`/`cleaner`/
/// `account`; tearDown deletes the account (cascading all its data). Tests that
/// gate on a residence existing set `requiresResidence` so one is seeded BEFORE
/// login (a fresh account is otherwise empty until a manual refresh).
