+Windows-specific dynamic link library dependencies.
+
+The Windows workflows copy everything in this folder into the final `release-64/libs`
+output. If required runtime DLLs are missing here, Windows builds will succeed but the
+published artifact will launch with missing-library errors. Make sure the proprietary
+or prebuilt DLLs the application depends on (e.g., bundled plugin runtimes) are added
+before cutting a release.
