Nuxt's dev vite-node IPC uses a unix socket under $TMPDIR. macOS's default /var/folders/… tmp dir pushes the path to ~110 chars, past the ~104-char sun_path limit, so every request 500s with 'connect EINVAL'. Point $TMPDIR at /tmp on darwin (guarded; other platforms untouched) before the builder generates the socket path.
