This page represents the iframe domain (our-site-but-not-forma-instance.com) that is embedded within the parent page from a different domain (not-our-site.com). SSO authentication loads automatically when configuration is received from the parent page.
Domain simulation:
Automatic Process: Cookie testing → SSO URL generation → Direct redirect (no button interaction required)
Expected Issues: CORS restrictions, third-party cookie blocking, cross-site redirect failures, localStorage access limitations
