+Demo: automatic nice-number axis bounds in range_frame
+======================================================
+
+This script demonstrates the ``nice=True`` feature of ``range_frame``.
+With ``nice=True`` (the default), spine bounds snap to tick positions so
+that the axis line starts and ends exactly on round numbers.
+
+The LEFT column uses nice=True  → spines always land on tick marks.
+The RIGHT column uses nice=False → spines sit at raw data min/max
+(the old behaviour, shown for comparison — tick misalignment is expected).
