+# This workflow exists to trigger the upload_artifacts workflow on both pull requests and push
+# events. It solves the issue of forked PRs not having access to secrets. Since external
+# contributors don’t have permission to access secrets, this dummy workflow runs with their
+# privileges and triggers the upload_artifacts workflow via the workflow_run event.
+# The upload_artifacts workflow runs in the context of the main branch, where it has access to
+# the necessary secrets for uploading artifacts, providing a secure solution for managing artifacts
+# in forked PRs.
