"""Root test configuration.

Auto-marks tests whose module imports from the ``playwright`` package with
the ``ui`` marker so they are excluded from the default ``make test`` run.

Also disables Panelini background images session-wide to skip the ~530 KB
base64 CSS injection that otherwise fires at every ``Panelini(...)`` call.
Unit tests in ``test_main.py`` pass explicit values and are unaffected.
