+"""Test that the detachable decorator and Plot.save work with detach=True.
+
+The original implementation used multiprocessing.Process which fails on Python 3.14
+due to a pickling error: `@wraps(func)` preserves `__qualname__`, so pickle resolves
+`Plot.plot` by name and finds the wrapper instead of the original function.
+
+Replacing Process with Thread avoids pickling entirely — figure saving doesn't need
