The body classes include:

id-1110 
_64-characters--css-allows-all-non-ascii- 
_64-characters-▶-css-allows-all-non-ascii-😑

In the child theme style.css, the related rule is:

._64-characters-▶-css-allows-all-non-ascii-😑 h1 {
	text-transform: uppercase;
	color: green;
}

It works in Twenty Twenty-Two when AMP is off.
