     * Determines how session restoration is handled.
     * Session restoration allows users to stay logged in between visits
     * without needing to explicitly sign in each time.
     *
     * Options:
     *
     * - **"auto" (default)**:
     *   Automatically selects the best method.
     *   If the app’s domain shares a common parent domain with the authorization endpoint,
     *   an iframe is used for silent session restoration.
     *   Otherwise, a full-page redirect is used.
     *
     * - **"full page redirect"**:
     *   Forces full-page reloads for session restoration.
     *   Use this if your application is served with a restrictive CSP
     *   (e.g., `Content-Security-Policy: frame-ancestors "none"`)
     *   or `X-Frame-Options: DENY`, and you cannot modify those headers.
     *   This mode provides a slightly less seamless UX and will lead oidc-spa to
     *   store tokens in `localStorage` if multiple OIDC clients are used
     *   (e.g., your app communicates with several APIs).
     *
     * - **"iframe"**:
     *   Forces iframe-based session restoration.
     *   In development, if you go in your browser setting and allow your auth server’s domain
     *   to set third-party cookies this value will let you test your app
     *   with the local dev server as it will behave in production.
     *
