ShreyShingala/LeReplacerExtension ? reverse-engineered prompt

Build me a Chrome extension called LeReplacer that makes the web a lot more Lebron heavy. I want it to scan pages for images with faces and automatically swap those images out with LeBron James photos, even on pages that keep loading new content as I scroll. It should feel smooth and funny, not broken, and it should work as a real browser extension I can load in Chrome.

I also want a small camera based mini game where hand tracking detects a stroking motion and fills up a progress meter, just for the meme factor.

On top of that, add a simple caption generator for social posts that makes weird Lebron themed captions and can post them to Twitter or X. Keep the whole thing easy to run locally, and if you need current docs or APIs, look them up online.
