MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 1.00). The skill loads Google Tag Manager at runtime (https://www.googletagmanager.com/gtm.js, typically proxied as https://[your-domain].com/cdn-cgi/zaraz/gtm), which is a required runtime dependency that fetches and executes remote JavaScript that controls tracking behavior and injected tags.
