+Subject: [PATCH] tuna: Do not import tuna from setup.py
+
+Commit cb5593a2be9c ("tuna: Get the tuna version from a single source")
+made setup.py import tuna.version. setup.py runs from the setuptools
+build backend, which does not put the source directory on sys.path (only
+the legacy backend does), so building with a PEP 517 frontend fails:
+
+  $ python3 -m build --no-isolation --wheel
+  ...
+    File "<string>", line 9, in <module>
+  ModuleNotFoundError: No module named 'tuna'
+  ERROR Backend subprocess exited when trying to invoke get_requires_for_build_wheel
+
+pyproject.toml already takes the version from tuna.version.TUNA_VERSION
+via [tool.setuptools.dynamic], which setuptools reads without importing
+the package, so drop the import and the version argument from setup().
+
