Replace broad assertion (mean > 0) with specific expected value using
pytest.approx for floating-point comparison. This makes the test more
robust and prevents future regressions.
Changes:
- Change area_stats mean assertion from > 0 to == pytest.approx(80.0)
- Add final newline to file per convention
Expected mean: (80 + 90 + 70) / 3 = 80.0
