+        Scoped CSS (`.razor.css`) is bundled into `$(AssemblyName).styles.css`, which App.razor links.
+        That bundle is generated at build time, so it never lives in the source tree's wwwroot. The
+        release build, though, serves static files solely from the ManifestEmbeddedFileProvider (see
+        Program.cs), fed by the `wwwroot\**` EmbeddedResource above. Without this target the bundle is
+        therefore missing at runtime and every scoped rule is dropped without a word, while the debug
+        build keeps working through the static web assets. Hence: build the bundle, then embed it
+        before the manifest is written.
