"""Phase 61 E2E (Playwright): the retired homelab-era copy is gone — the
visitor SEES the locked neutral copy on the shared default server.

Story: n/a (TODO-derived — TODO.md L4 "Clean up the UI, there's text
that references old features…"). Run in isolation (DB must be up:
``podman compose up -d db``):

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

The shared conftest server boots with the default env — and the code
defaults are exactly this phase's locked copy (A1/A2; the conftest
forces ``BOR_SUGGESTIONS`` from the ``Settings`` field so an operator's
local ``.env`` cannot leak corpus-specific chips). Every assertion is a
settled-state check: static HTML + one ``GET /api/suggestions`` fetch;
Playwright's ``expect`` retries ride out the chip rendering.

Test → lock mapping (Playwright Mapping Rule):
1. ``test_chat_page_placeholder_meta_footer_are_the_locked_copy``
2. ``test_chat_page_shows_no_homelab_or_deployment_text``
3. ``test_chat_page_suggestion_chips_are_the_locked_list``
4. ``test_sources_page_sub_describes_the_current_source_model``
5. ``test_git_sources_example_url_is_neutral``
