                the instant `user` becomes truthy, the dialog is destroyed and the
                skater is dumped on the map with no recovery step — the exact bug
                reported. So we keep LoginArea mounted always and just hide its
                trigger when logged in; MobileHeaderUserMenu becomes the visible
                control. The dialog renders in a portal, so hiding the trigger is
                purely cosmetic and never interrupts an in-progress signup. */}
