"""Phase B browser journey (US02-07): start a content-analysis job from the Analyze
view and watch live progress arrive over the real SSE adapter, against a real server
and durable worker. The frontend's SSE→polling event adapter and the worker are
exercised end to end; the vision edge is the recording fake.
