DJHanceNL/Future-Roop ? reverse-engineered prompt

Build me a desktop app for face swapping called Future Roop, based on the idea of roop unleashed. I want a simple browser style interface where I can load one or more source faces and swap them into images or videos, then preview the result before saving it. It should support batch processing, different ways to choose faces, and a live webcam mode for a fake cam effect. Add options for masking awkward parts like hands or occluders, plus some kind of face enhancement or upscaling if available. I also want an extras section for simple video tools, a settings page that remembers my choices next time, and a few theme options so it looks nice.

Make it easy to run on Windows, and if you need to check current setup details or library docs online, go ahead. Please keep the app polished, with clear buttons, status messages, and sensible defaults so a regular person can use it without much setup.
