+name: 🚀 Release Fork Packages
+
+# Publishes ONLY the forked StrawberryShake packages, renamed under the Stackworx.* prefix:
+#   * Stackworx.StrawberryShake.Razor   - runtime base classes
+#   * Stackworx.StrawberryShake.Blazor  - meta package; bundles the patched dotnet-graphql tool
+#   * Stackworx.StrawberryShake.Tools   - dotnet-graphql CLI
+# Everything else is consumed from upstream nuget.org. See FORK.md "Packaging & publishing".
+#
+# How to run:
+#   * Manually: Actions -> "Release Fork Packages" -> Run workflow; pick the ref to publish
+#     (e.g. release/fork-16.3.0) and the version.
+#   * By tag:   push a tag like `fork-16.3.0` on the ref you want to publish (the version is the
+#     tag minus the `fork-` prefix).
+# Publishes via NuGet trusted publishing (OIDC) using the NuGet/login action; requires the
+# `NUGET_USER` organization variable and a trusted-publishing policy on nuget.org per package.
