+<!--
+  Repository-level NuGet.Config to control which sources are queried for which
+  packages. This prevents the GitLab feed from being queried for all package
+  IDs (which causes 401 errors for packages hosted on nuget.org).
+
+  Usage:
+  - Keep this file in the repository root so `dotnet restore` picks it up by default.
+  - CI still needs to add the `GitLab` source credentials at runtime (we do this
+    from the pipeline using `dotnet nuget add source ...`), but the mapping below
+    ensures only the listed package ID patterns are requested from the GitLab feed.
