Build me a simple TikTok themed landing page that feels like a fun little prank site. It should look clean on mobile and desktop, with a bold headline, a short description, and a clear button that makes the page feel interactive. When someone opens it, show their public IP address and a few basic details like browser and device in a simple card on the page, and make it easy to copy or share the result.

Keep everything in plain HTML, CSS, and JavaScript so it works as a static site in the public folder. Make the design look modern, dark, and social media inspired, with some subtle motion and a polished button state. If you need to use a public API for the IP lookup, go ahead and look up current docs online first. Also make sure it handles errors nicely and still looks good if the lookup fails.
