# Install Solana CLI (release.solana.com is defunct; Anza now hosts the installer).
# Pinned to v2.1.21, not "stable": Agave 3.x+ added a hard dependency on io_uring
# that panics (assertion failed: io_uring_supported()) in containers where io_uring
# syscalls are blocked by the default seccomp profile, which we cannot override on
# Hugging Face Spaces since we don't control the `docker run` invocation.
