+/// When using `uv pip compile --python-platform`, it should not matter what platform the built
+/// wheel is for. We want to ensure that uv accepts both wheels for the host platform and wheels for
+/// the target platform in `uv pip compile`. This is unlike `uv pip install --python-platform`,
+/// where a wheel for the target platform is required.
+///
+/// The main test (first snapshot) builds a Windows wheel, and targets macOS. If we run this test on
+/// Linux, the wheel tag is neither host nor target, but we don't have a reason to reject the
+/// Windows tag either.
