+# Based on upstream's wheel builder:
+#   https://github.com/Quansight-Labs/pyyaml-ft/blob/v8.0.0/.github/workflows/ci.yaml
+# Upstream builds a static libyaml itself (packaging/build/libyaml.sh) and links the
+# Cython extension against it; we do the same here. Only cp313/cp313t are in upstream's
+# own matrix; the riscv64 image has no cp313t interpreter (gotcha 11), so cp314t stands
+# in as the free-threaded target, same pattern as build-bcrypt.yml.
