+# build-rc-local-win.ps1 — build the Windows Velopack Portable.zip LOCALLY, no publish, no token.
+#
+# Mirrors the win-x64 build-pack job in .github/workflows/release.yml (the source of truth), minus the
+# compliance evidence (SBOM/license corpus), the delta-base download, and the upload. Produces the same
+# Portable.zip a real release would, so you can smoke-test Windows before cutting the tag.
+#
+# Run from anywhere inside the repo in PowerShell 7:   pwsh .\publish\build-rc-local-win.ps1
+#
+# Prerequisites on this machine:
+#   - .NET 10 SDK (matching global.json), pnpm, Node 22
+#   - To actually RUN the packaged app: ASP.NET Core Runtime 10.0.10+ (x64). The build is
+#     framework-dependent and does NOT bundle the runtime — that is by design.
+#   - vpk (Velopack CLI) 1.2.0 — this script installs it if missing.
+
+#Requires -Version 7.0
