There's no path yet to add a second real identity to this workspace. Each signed-in identity is bound to exactly one tenant at the database level (`tenant_users_sub_uniq`), and a first sign-in always provisions its own new tenant — so a real invite-and-join flow needs a deliberate change to that binding, not just this page. Not built in this pass; reported rather than faked.

The blurb names it; the codebase doesn't have a concept for it yet — no shared-memory store exists to wire this to. Reported as a future item rather than invented here.
