🚀 Features:
✅ Detects localhost, 127.0.0.1, .docker, and dev. domains.
✅ Displays a red warning banner with “This is a local or development page!” message.
✅ Prevents accidental modifications or actions in non-production environments.
✅ Works automatically on all web pages without additional setup.
Perfect for developers, testers, and teams working with local or staging environments!
🔧 How to use:

2. Open any local or development site (e.g., http://localhost, http://xxxx.docker, https://dev.xxxx).
3. See the warning banner at the top of the page.
⚠️ Note: This extension does not modify site functionality—it only adds a visual indicator to prevent mistakes.
