- User-facing strings are pulled from `Properties.Resources.*` through generated `Resources.Designer.cs` rather than being hard-coded, enabling per-culture `.resx` files.
- UI state updates are marshaled onto the dispatcher via `_dispatcher.Invoke(() => ...)` before touching `ObservableCollection<string> Items` from background tasks.
- ViewModel properties expose change notification through a shared generic `SetProperty<T>(ref T obj, T value, [CallerMemberName])` helper paired with `OnPropertyChanged`.
- CLI options are declared as POCO properties decorated with `[Option(...)]` attributes consumed by `Parser.Default.ParseArguments<Options>()` at startup.
