EvanKoe/expressive-cutout ? reverse-engineered prompt

Build me an Android app that turns the camera cutout into a dynamic island style overlay, inspired by Apple but using Google’s Material Expressive look. It should run fully on device, with no internet use, and guide the user through the needed permissions on first launch, like notification access and accessibility so the overlay can work reliably.

I want it to show mirrored notifications, music info and controls, phone call info, timer updates, assistant replies, and a few system events like charging, Wi Fi, headphones, USB, and unlock. Please make it customizable too, with options for size, position, rounded corners, colors, shadows, animations, and per app controls. If it helps, look up current Android and Compose docs online while building it. Make the experience feel polished, smooth, and privacy focused, with a live preview in settings and a clean Material You style throughout.
