CI pipeline failing - please fix

[juninmd]

Issue Body:
The Deploy VitePress site to Pages workflow failed in the last 24h. Investigate the following:

1. Check the vite.config.js for correct Pages deployment configuration.
2. Verify environment variables (e.g., PAGES_API_KEY) are set correctly.
3. Ensure the workflow uses the correct command (vite build or vite preview) and dependencies are installed.
4. Test the workflow locally to confirm setup is correct.

Suggestion: Update the workflow to explicitly include vite build and verify Pages deployment settings in the GitHub Pages configuration.
