GitHub wouldn't let me upload an .html file, so I added a .txt suffix. You should be able to rename it locally and open in your favorite browser of choice.
I did a quick scan and nothing looked suspicious, but I'll leave it to y'all to determine if anything looks concerning on the stage env and might affect production in any way.

Semi related, but I also did a Google Lighthouse audit of staging and it got 3× 💯 scores, and a 90 for SEO (mainly because I think we prevent crawlers from indexing non-production sites). So I ignorantly assume it'll be four-hundred on production.

Start with the attached webhint report and the staging URL, then review the listed errors and warnings to determine which findings affect the application or production configuration. Done means the relevant findings are resolved or explicitly triaged for production, with the remaining items explained.
