+# --- Step 5b: Stable-named installer alias for the website download button ---
+# electron-builder's Squirrel target ignores `artifactName`, so the installer
+# ships as `openswarm-Setup-<version>.exe` (lowercase, version-stamped). The
+# openswarm.com Windows button links to a fixed name, so without this alias
+# every release 404s. The DMG target DOES honor artifactName, which is why
+# macOS never hit this. The alias is a byte copy of the already-signed
+# installer (signature preserved) and is invisible to the Squirrel updater,
+# which keys off RELEASES + .nupkg, not the installer filename.
