+# manylinux_2_28 and musllinux_1_2 only. Inside a 2014 container pip
+# therefore falls back to the numpy sdist and tries to compile it, which
+# fails outright because that image ships GCC 10.2.1 and numpy requires
+# >= 10.3. Pinning the images to numpy's own floor is what makes the wheel
+# installable: LZGraphs cannot run without numpy, so being more permissive
+# than numpy buys nothing and only produces a wheel whose dependency will
