The observe step now has an inner loop — if the page isn't ready (still
loading, wrong URL, expected content missing), the agent loops back to
observe again instead of acting on stale state. The ASCII diagram shows
the 'not ready' branch looping back to observe.
Every observe step in the example now prints page.url() before the
snapshot so the agent always knows the current URL. This catches
redirects and unexpected navigation between actions.
