iamEtornam/EtornamVpnFlutter ? reverse-engineered prompt

Build me a Flutter app that matches a stylish VPN app mockup, like the one shown in the screenshots. I want it to feel polished and modern, with a clean home screen, big connection status area, attractive buttons, and a smooth mobile first layout that works on Android and iPhone.

Please make the app switch between light and dark mode automatically based on the system theme, and keep the design consistent throughout. Use the assets and screenshots already in the project if they help, and make the UI look close to the reference design rather than plain or generic.

If there are any small missing details from the design, make sensible choices so the app still feels complete. Keep it simple enough that I can run it right away with Flutter, and if you need current Flutter guidance, look up the latest docs online.
