 - fetch a URL inside n8n
 - normalize content into a predictable summary-ready shape

+- `skip_ssl_certificate_validation` is optional and defaults to `false`
+- set it to `true` only when you explicitly need to work around broken/missing CA trust in the n8n runtime
+- for a stable local smoke test, prefer an HTTP URL you control such as the local n8n `/healthz` endpoint

 - `url`
 - `title`
