  <!--
    Common pack-time items for NAudio NuGet packages. The icon is anchored
    to the repo root via $(MSBuildThisFileDirectory) so it resolves
    correctly from any csproj depth. The README include is conditional on
    a README.md sitting next to the csproj — NAudio packages each have
    their own per-package README; tool/test projects don't, so the
    conditional include is silently inert for them.

  <!--
    If PackageReleaseNotesFile is supplied (e.g. by the release workflow
    passing -p:PackageReleaseNotesFile=<path>), load its contents into
    PackageReleaseNotes so NuGet displays them on the package page.
    No-op when the property is unset or the file is missing, so local
    `dotnet pack` keeps working with no extra setup.
