"""Phase 16 E2E (Playwright): single-admin sign-in (A10 revised).

Story: ``.agent/user_stories/admin-auth.md``
Run in isolation (DB must be up: ``podman compose up -d db``):

    uv run pytest tests/e2e/test_admin_auth.py -v --no-cov

The E2E app server boots with ``BOR_ADMIN_PASSWORD``/``BOR_SESSION_SECRET``
set (``tests/e2e/conftest.py``); the shared ``tests/e2e/auth_helpers.py::login``
performs the real form login on /login.html.

Test → story mapping (Playwright Mapping Rule):
1. ``test_anonymous_chat_without_tuning``
2. ``test_anonymous_sources_gated_viewer_open``
3. ``test_login_wrong_password_shows_error``
4. ``test_admin_login_unlocks_sources_and_tuning``
5. ``test_logout_returns_to_anonymous``
