Loading nipplejs from CDN creates an external dependency that could fail or be compromised. For a truly self-contained solution, consider downloading and embedding the library or using a local copy.

The JavaScript code is embedded as a heredoc within the YAML workflow, making it difficult to maintain and debug. Consider creating a separate .js file in the repository or using a more structured approach.

Using --force-with-lease can overwrite changes if the remote branch has moved. Consider using a regular git push first and only fall back to force push if necessary, or implement proper conflict resolution.

Loading external JavaScript from CDN without integrity verification poses a security risk. Consider using Subresource Integrity (SRI) hashes or bundling the library locally for production use.
