/*
    Shared harness for the Cine Studio E2E specs.

    Each spec is a standalone runnable Node script (so it works both via
    `node run.js` and directly, e.g. `CS_BASE_URL=... node specs/functional.js`).
    The harness centralizes browser launch, app navigation and the
    pass/fail reporting helpers.

    Env:
      CS_BASE_URL       base URL the app is served from (default :8123)
      PW_CHROMIUM_PATH  optional explicit Chromium binary; otherwise
                        Playwright resolves its own installed browser
