Two roads diverged in a merge conflict and I took the wrong one.

It seems Pyodide no longer ships its own wheels for Python 3.15,
presumably because PyPI now supports WASM wheels and it's expected for
upstreams to release them.

Unfortunately, our upstreams (at least contourpy and kiwisolver) don't
yet have those wheels, so our wasm build fails and we haven't been
uploading nightlies for the past few days.
