+# Dockerfile.build-paddle-cpu - Build PaddlePaddle CPU wheel for ARM64
+#
+# Required because PyPI wheels don't work on ARM64 (x86 SSE instructions).
+#
+# Build time: ~1-2 hours
+# Output: /output/paddlepaddle-*.whl
+#
+# Usage:
+#   docker build -t paddle-builder:cpu-arm64 -f Dockerfile.build-paddle-cpu .
+#   docker run --rm -v ./wheels:/wheels paddle-builder:cpu-arm64
