+ * appears, regardless of how many Customer (business) accounts they're linked to.
+ * Deliberately carries no customerId: a provider that needs to know which
+ * Customer accounts this User is linked to (e.g. to detach them, or to find data
+ * keyed by a shared email) looks that up itself, rather than this value object
+ * assuming one fixed Customer — the whole point is that one User can belong to

+ * assume or privilege any single one of them.
