🧪 Test-box note: Box DNS resolves public hosts to 198.18.x (egress proxy), which the fetch server's private-IP guard refuses; --allow-private-ips is used on this box only. Published snippet omits it. Default (readability) mode failed on this box: node ExtractArticle.js exited 1 (see results/protocol/ref-fetch.default-mode.json); check uses raw=true.
