## How to Verify Zero Network Egress Yourself
1. Open DevTools by pressing F12 or Right-Click > Inspect.
2. Switch to the **Network** tab.
3. Check the **Preserve log** option and filter by **Fetch/XHR**.
4. Disconnect your internet connection (or enable Airplane Mode / Offline throttling).
5. Load a file, convert structured data, inspect an X.509 certificate, or calculate cryptographic hashes.
6. Notice that **zero network requests** are dispatched during any tool operation.
