samfoundsus/Compass ? reverse-engineered prompt

Build me a minimal Android compass app that feels clean, modern, and a little like Pixel and Material You. It should show a live compass dial that rotates smoothly as the phone moves, with both Magnetic North and True North modes, and it should figure out magnetic declination automatically using the device location when needed.

I want a few nice customization options too, like light, dark, and system theme, an AMOLED style dark mode, dynamic wallpaper based colors, and a choice of four dial looks, Sunny, Circle, Diamond, and Octagon. Let me lock the dial in place if I want, and add optional haptic feedback plus calibration support. Save the user settings so they stick.

Also include home screen widgets that match the main app, support the same dial styles, use dynamic colors, and open the app when tapped. Keep the whole thing simple, polished, and focused on the compass experience. If you need current Android guidance, look up the latest docs online.
