Build me a lightweight Android app that wraps Facebook in a simple browser experience.

I want it to open Facebook, let me switch between mobile and desktop view, and include easy cookie tools so I can view, copy, edit, and export cookies in String, Netscape, or JSON format. It should also let me set a custom user agent, and support dark, light, and system theme modes.

Keep the app clean and fast, with a straightforward interface that feels like a small utility rather than a full browser. Make sure it works well on Android, and include a way to log in and manage the Facebook session inside the app.

If you need current Android or WebView docs while building it, look them up online.
