📋 USAGE EXAMPLES

Example 1 - Popup Mode:
You receive a "password reset" email from what looks like PayPal. You click the link, and a dialog shows: "You are about to visit: http://paypa1.fake-site.com" - the "l" is actually a "1"! You realize it's fake and click Cancel.

Example 2 - Warning Banner:
An email from "support@microoft.com" arrives (notice the typo). A huge red warning banner appears: "CAUTION: NON-TRUSTED SENDER" - immediately alerting you before you even read the email.

Example 3 - Trusted Whitelist:
You add "amazon.com" to your trusted list. Now all legitimate Amazon tracking links work normally with a green checkmark, while suspicious lookalike domains are still blocked.
