/**
 * Performance journeys (docs/architecture/performance-journeys.md). One
 * worker, no retries: every journey spawns its own Electron processes and
 * adds its entry to the run's single summary file. The Xtream mock serves both the M3U playlist
 * and the portal on a dedicated loopback port so a normal E2E server on
 * 3211 cannot be reused by accident. The mock runs as one node process
 * rather than through `nx run …:serve`, whose detached process group outlived
 * the run and kept the port. Locally a server already on the port (e.g. one
 * started by hand) is reused, since its fixtures are deterministic; CI always
 * starts its own.
