March 2025: Delivered a targeted bug fix to improve CI/CD deployment preview reliability for the pan.dev project. Resolved a misconfiguration in the GitHub Actions workflow by correcting the artifact pinning (ensuring the correct download-artifact action is used rather than the erroneously pinned upload-artifact). This fix stabilizes deployment previews and provides consistent feedback for PRs and stakeholders.
