Observe on-device

  1. Does /book render inside the frame at all, or does it refuse?
  2. Can you sign in inside the frame (email/password)?
  3. Does "Continue with Google" work inside the frame, or refuse? (Expected: refuse — Google blocks OAuth in iframes.)
  4. Does the Stripe payment form (Elements) render inside the frame?
  5. Does a real test-card payment complete inside the frame?
  6. If 3DS triggers, what happens — does the challenge render, and where do you land afterward?
  7. Does anything break out of the frame to top-level unexpectedly?
  8. Safari-specific: after signing in, reload the page — is the session still there, or did storage partitioning drop it?
