Create an interactive AR study aid for physical therapy students. The app should let me drop a life‑size 3D musculoskeletal model into my room, walk around it, and tap any muscle to open an info card with key details (name, origin/insertion, function, common injuries). I want short exercise animations that show how muscle groups work together. It must feel realistic and dependable: accurate scale, stable tracking, and believable lighting, all running smoothly. Everything has to work offline—bundle the 3D models and anatomy data in the app. Use SwiftUI for the on‑screen information overlays, and you may add lightweight helper libraries via CocoaPods if needed.
