/**
 * v1.16.8 — the auth cell retries ONCE on transient failures.
 *
 * `useAuth` used to pin `retry: false`, so one transient network blip
 * on `/api/auth/me` flipped `isAuthenticated` false and sent the shell
 * to the redirect spinner mid-session. The cell now uses the shared
 * transient-retry predicate: one retry on network errors / 5xx, never
 * on 401/403 (those are real answers).
