Man, that is the first time that bot has be used. It is ruthless. Haha, I will review this soon.

Perhaps it would be helpful to show GitLab CI's output to verify .UniqueID → .File.UniqueID.

On my end everything works except reCAPTCHA. Is there anything special - is it reCAPTCHA v3?

{"success":false,"message":"reCAPTCHA: The response parameter is invalid or malformed","rawError":{"_smErrorCode":"invalid-input-response"},"errorCode":"RECAPTCHA_INVALID_INPUT_RESPONSE"}

[VincentTam]

Overall speaking, I've not touched your code about reCAPTCHA v3, which I've never tried, so I can't comment. Btw, this PR is meant to be an analogue of mmistakes/minimal-mistakes#1845, and the Go-HTML code in this PR does its work of getting the site config parameters into the generate HTML pages. reCAPTCHA is another issue.

[pacollins]

I see now. I will just need to revert to reCAPTCHA v2.

Thanks for all of this.
