+# Phase 1: build unsigned Windows installers on demand, upload as run artifacts.
+#
+# To graduate to Phase 2 (signed + published to GCS):
+#   1. Add GCP auth step (`google-github-actions/auth@v2` via WIF) + `setup-gcloud`.
+#      Swap `yarn make:win` for a new `yarn release:win` script that runs
+#      `electron-forge publish` per arch and a gsutil cache-control step.
+#   2. Add an Azure Trusted Signing setup step that downloads the
+#      Microsoft.Trusted.Signing.Client dlib and writes a metadata JSON file,
+#      then exports AZURE_DLIB_PATH + AZURE_METADATA_JSON_PATH. Set
+#      AZURE_TENANT_ID / AZURE_CLIENT_ID / AZURE_CLIENT_SECRET from secrets.
+#      The dormant `windowsSign` branch in js/forge.config.ts activates
+#      automatically once AZURE_METADATA_JSON_PATH is set.
