-			Expected Warning: "Missing Palaso native files"
-			These are Windows-only native interop DLLs for optional features:
-			- Keyman*Interop.dll, KeymanLink.dll: Keyman keyboard integration
-			- irrKlang.NET4.dll: Audio playback via irrKlang engine
-			- Interop.WIA.dll: Windows Image Acquisition for scanning
-			- NDesk.DBus.dll.config: Linux D-Bus configuration (not needed on Windows)
-
-			This warning is EXPECTED in CI environments where:
-			1. These optional native dependencies aren't installed
-			2. The NuGet packages don't include all platform-specific files
-			3. Full functionality requires a complete Windows development environment
-
-			The warning does NOT fail the build. Features using these DLLs will gracefully
-			degrade or show appropriate error messages at runtime if the files are missing.
