    # 8-core runner so the 4 Playwright workers (see playwright.config.ts) have
    # CPU headroom alongside the app + ClickHouse + MongoDB — 4 workers
    # over-subscribed the 4-vCPU ubuntu-24.04 runner and caused timeouts.
    # RUNNER_E2E is a label or a JSON array of labels. On a smaller
    # runner, set the E2E_WORKERS variable to 2 as well.
    # Fork PRs can't use the custom runner group and would queue forever, so
    # they fall back to the 4-vCPU ubuntu-24.04 runner with 2 workers and a
    # longer timeout.
