   I propose just changing the `target-cpu` on ARM builds to `neoverse-n1` 
which gets you LSE (atomics) and is a reasonable baseline for ARM architectures 
available in 2026 from cloud vendors. It's also a subset of what Apple Silicon 
provides. Newer `neoverse` targets would be great, but I don't know if we want 
to require new Graviton and eliminate stuff like Ampere Altra. I'd need to do a 
survey of GCP and Azure ARM cores.
