# Env:     RUSTFLAGS   extra rustc flags (optional)
#          NIGHTLY=1   build with nightly + -Z build-std (for tier-3 targets)
#          DIST_DIR    output directory (default: dist)

# This is the single source of truth for artifact naming, shared by the CI
# workflow and the local/podman build scripts.
