# The repo's .cargo/config.toml sets `target-cpu=native` for local M1 dev.
# On GitHub's heterogeneous shared-runner fleet that flag makes rustc emit
# instructions the underlying (often live-migrated) silicon can't execute,
# so the verification build dies with SIGILL. Every other workflow
# (ci/release/bench) overrides it with a portable baseline; publish.yml was
# the one that didn't. Match them so the publish gate is reproducible.
