Why it surfaced

liluser uses a real browser, signs up, confirms email, and attempts a task like a first-time user—then verifies side effects such as whether the confirmation email actually arrived. Its reports include screenshots, and the tool can run from an API, CLI, or GitHub Action against staging or preview deployments.
