ogemboeugene/FaceSwap ? reverse-engineered prompt

Build me a web app that can do live face swapping in the browser.

I want it to ask for camera permission, show the live camera feed, detect faces in real time, and swap my face with either a built in celebrity face gallery or a face I upload myself. It should keep my expressions looking natural, work smoothly on desktop and mobile, and let me take a photo of the result when I like it. Please include a clean modern interface with light and dark mode, simple controls for things like quality and blending, and make it feel polished and easy to use.

Use React and TypeScript, with a fast setup that can run locally in the browser, and keep the face processing on the client side for privacy. If you need current library details or docs, look them up online and use the best approach.
