      # v1.4.16 C5 — drop linux/arm64 from the multi-arch build.
      #
      # Root cause of the main-branch hang since v1.4.14: the qemu-arm64
      # path (`docker/setup-qemu-action` + `tonistiigi/binfmt`) was
      # SIGILL-crashing Next.js's static-page-generation workers
      # (`Next.js build worker exited with code: null and signal: SIGILL`
      # at 64-66/86 pages). V8's optimising tier emits CPU instructions
      # that qemu's user-mode emulation cannot reliably translate under
      # heavy load, and Node 22 + Alpine 3.21 hit it deterministically.
      # Tag-builds appeared to "work" only because they happened to
      # finish their static pages before the crash window; main-branch
      # builds rarely got that lucky.
      #
      # Marc's prod target is x86_64 only (Coolify on apps-01, all other
      # self-hosted instances we know of); the arm64 image was a
      # courtesy build for OSS users, not production. v1.5 will re-add
      # arm64 via a matrix that uses the GitHub-hosted `ubuntu-24.04-arm`
      # runner (free for public repos, native arm64, no qemu) — see
      # `docs/audit/v1416-auto-deploy-fix.md` for the broader CI plan.
      #
      # Per-ref gha cache scope (kept from v1.4.15 C3): tag + main
      # builds at the same SHA do not contend on writes; tag warm-starts
      # off main's last good build for layer reuse.
