 * for a session and a permission, and nothing more: any member could wipe the
 * workshop's records, export the whole organisation or replace it with an
 * empty backup, change the plan and charge the card, and a settings manager
 * could invite a second address of their own as admin. All of them are
 * owner-or-admin decisions now, whatever permissions a custom role carries.
 *
 * So a colleague is given a role with every permission the app knows and no
 * admin standing, which is the member every permission check waves through,
 * and is then pointed at each of those doors.
