/**
 * Layer 2 of the record/replay e2e: the REAL Next.js frontend rendering data
 * from a REAL gateway whose LLM is the deterministic `ReplayChatModel` (no API
 * key). This is separate from `playwright.config.ts` (which mocks the backend)
 * so the mock-based suite is untouched.
 *
 * Two webServers are started: the replay gateway and the frontend pointed at
 * it. Auth-disabled mode is enabled on both servers so the no-cookie e2e
 * contract is covered; specs that need session cookies still register a
 * throwaway test account at runtime.
