Build me a fun Valentine’s Day hug detector app for a Jetson Nano with a camera.

It should watch the live camera feed, recognize when two people are hugging, then start a short countdown, take a cute polaroid style photo, and show it in a retro pixel art interface with hearts, clouds, and a pink themed overlay. After the photo is captured, it should send a simple serial signal to an Arduino so it can trigger a candy dispenser. Also save each photo into a local album that the user can browse on screen.

Please make the app run smoothly in real time, with face detection happening in the background so the display stays responsive. I want it to feel like a polished little hackathon demo, with a playful love themed look and a clear state flow from live view to countdown, flash, photo, and album. If you need to look up any current docs online, go for it.
