/** The ✦ share toggle's state: which tenant the menu offers, whether the share
 *  is on, and the write. ONE request answers all three (`GET /apps/:id/grants`
 *  carries the caller's own memberships), so the menu never guesses.
 *
 *  Nothing is offered unless there is something to offer: a non-owner may not
 *  share, and a caller in no tenant has nobody to share with. Both answer
 *  `undefined`, and the menu item simply does not render. */
