Platform Targets

Platform	Build Host	Notes
Android	Windows/Mac	Emulator or device
iOS	Mac only	Requires Xcode
macOS	Mac only	Catalyst
Windows	Windows	WinUI 3

Workflow

Confirm target platforms — behavior differs across Android, iOS, Mac, Windows
Separate shared UI and platform code — use handlers and DI
Follow MVVM pattern — keep views dumb, logic in ViewModels
Handle lifecycle and permissions — platform contracts need testing
Test on real devices — emulators don't catch everything
