SwiftUI MVVM Demo App

I’m putting together a lightweight, single-screen iOS showcase that cleanly demonstrates MVVM, Combine, and SwiftUI best practices. The app will fetch data from my REST endpoint, then present it in two distinct sections:

• A horizontally swipable 1-on-1 card carousel. Every card contains only text, and I’d like a subtle fade as the user moves from one card to the next.
• A vertically stacked FAQ where each question expands or collapses to reveal its answer—again, text only.

The focus is on readable, well-structured code: clear view models, proper dependency injection, async networking, graceful error handling, and tight SwiftUI layout. If a small mock or preview layer helps illustrate the architecture, feel free to include it. The finished project should run on the latest Xcode and iOS version, compile without warnings, and be easy for another developer to extend.
