joeconsorti/duo-fold-live ? reverse-engineered prompt

Build me an Android app for the Galaxy Z Fold 8 that creates a live folding wallpaper animation over the normal system and apps, without replacing the launcher.

I want the phone’s fold and unfold movement to drive a smooth glass style animation with a live cover screen preview, mirrored reflection, blur, black fade during the display handoff, and a few different animation modes like a default glass look, a simpler classic mode, and options that only animate on fold or only on unfold. Please include a setup flow that guides the user through the permissions and Samsung wallpaper steps it needs, plus Shizuku support, reconnect and recovery help, and a way to choose a custom photo wallpaper with previews for folded and unfolded states.

Also add a settings screen for tuning motion smoothness, blur, glass strength, anti aliasing, hinge thresholds, and keep awake behavior, along with a troubleshooting section for the display turning off during the transition. If anything needs current Android or Samsung docs, look them up online.
