      # NOTE: ui/tests/ is deliberately not run here. Those tests need
      # ui/data/analysis.json — pipeline output that is gitignored and never
      # ships — and ui/tests/test_ui.py additionally needs Playwright browsers.
      # Neither is available on a fresh clone. Run them locally after a full
      # pipeline run: `uv run pytest ui/tests/`. Making these runnable in CI
      # (via committed fixtures) would be a welcome contribution.
