// auth-gate.jsx — owns the "logged in or not" state.
//
// The SPA boots into <AuthGate>, which calls GET /auth/me. On 401 it then
// calls GET /auth/setup-required and renders <SetupScreen> or <LoginScreen>
// (defined in screens-auth.jsx, Task 16). On 200 it renders the real <App>.
//
// This component is the SINGLE source of truth for the auth check — no other
// component should redirect to a login page or wipe data on 401. Other code
// surfaces auth failure by calling window.AuthGate.bounce(), which re-mounts
// the gate so the next /auth/me request decides what to do.
