Classify each request as first-party (same registrable domain as the page) or third-party. Group third-party requests by their domain and sum transfer size + request count per domain. 4. Label well-known vendors by domain so the report is readable, e.g.: - `google-analytics.com`, `googletagmanager.com` → Analytics / Tag Manager - `doubleclick.net`, `googlesyndication.com` → Ads - `connect.facebook.net` → Meta Pixel - `intercom`, `crisp.chat`, `hotjar`, `fullstory` → Chat / Session replay - `optimizely`, `launchdarkly` → A/B / Flags 5.
