DrakK768/Procom-PHARE ? reverse-engineered prompt

Build me a Unity mobile app in augmented reality for visiting the Phare du Minou, where people can point their phone at printed posters and see two historical buildings appear in the real world, the old keeper’s house and the hotel. The app should work with image tracking on Android and iPhone, and when it detects the right poster it should place the matching 3D model in the correct spot and keep it anchored while the user moves around.

I also want a simple interface with a start screen, a side menu, a tutorial, and a bottom bar with a screenshot button. The screenshot should save the AR view without the UI. Add a manual adjustment mode too, so the user can move the model with one finger, pinch to change distance, and rotate it with two fingers. If it helps, look up current Unity and AR docs online before wiring it up.
