selop/pokebox ? reverse-engineered prompt

Build me a web app that lets people browse Pokemon TCG cards in a really cool holographic way. It should use the webcam to track head movement in the browser and make the card scene shift like a real parallax window, with shiny foil effects that react as you move. If the camera is blocked or denied, it should still work with keyboard and mouse controls, and on phones it should use tilt instead of the camera.

I want the experience to feel polished and playful, with a simple way to switch cards, share the current card with a link, and adjust the tracking so the effect feels right on different screens. Please make it run smoothly in the browser and keep all camera tracking private on the device. If you need to check current docs for the webcam or rendering pieces, look them up online.
