• SecureAuthStore (Keychain / Keystore via flutter_secure_storage) and PrefsAuthStore (shared preferences, for the web) keep the session across restarts.
• VaultbaseLifecycle: closes the realtime connection after 30 s in the background, reconnects and resubscribes on resume, and refreshes a session that expires within 5 minutes.
• signInWithOAuth2 on auth.collection(name): OAuth in the system's sign-in browser via flutter_web_auth_2, with server-kept PKCE. Closing the browser throws CancelledException.
• Re-exports package:vaultbase.
