Can one account belong to more than one organisation?

Underneath, a user and an organisation are linked by a separate membership record, which is designed to allow one person to belong to more than one organisation — useful if you run more than one business, or if you're invited as a member into someone else's.

Right now, the dashboard only ever looks up and shows your first membership, so there's no organisation switcher yet even though the underlying model supports it. An organisation-switching UI is planned once team invitations exist.
