Host/App.razor uses the kit's <ThemeHead/>/<ThemeScripts/>, but Host had no direct PackageReference — it relied on CentralUI re-exporting the package transitively. Add a versionless <PackageReference Include="ZB.MOM.WW.Theme"/> (version pinned by central PM at Directory.Packages.props) so the declared dependency matches actual usage and survives any future PrivateAssets/refactor on CentralUI. Additive only; Host builds clean (0/0).
