+# This workflow is currently disabled at the trigger level (no push /
+# pull_request handlers) because:
+#   1. ci.yml's compile-extensions-build step is parked (gulp-vinyl-zip +
+#      Open VSX hangs)
+#   2. We need a usable Zeus binary, which a packaged build provides
+#
+# Once compile-extensions-build is back and we have a dmg/AppImage step,
+# flip the trigger to push: main + weekly cron.
