+          # manylinux_riscv64 image doesn't carry, so both are pinned to binary --
+          # only our registry has them for riscv64. matplotlib (test-only) is pinned
+          # for the same reason: no public-PyPI riscv64 wheel, and it is slow to
+          # build from source. pillow (a matplotlib runtime dep, also test-only) is
+          # pinned too: unpinned, pip resolves PyPI's newest pillow -- which has no
+          # riscv64 wheel anywhere -- ahead of our registry's, and its sdist build
+          # fails outright (RequiredDependencyException: jpeg; the manylinux image
+          # carries no libjpeg headers). Cython (the other build-time requirement) is
+          # left unrestricted: our registry only carries riscv64 Cython wheels for
+          # cp312+, and letting pip fall back to Cython's own (portable,
+          # non-arch-specific) sdist for cp310/cp311 builds cleanly, as it already
+          # does for crick.
