# NOTE: `python-neo-lzf` currently lacks pre-built wheels for Linux aarch64.
# To avoid compilation errors on Linux ARM environments, we use `python-lzf` as a fallback.
# macOS ARM64 (Apple Silicon) is supported by `python-neo-lzf` (Universal2), so it is not affected.

# 1. Fallback: Use `python-lzf` ONLY on Linux ARM64.
