Great work! Just two minor notes. Thanks so much for the issue creation and work on this.

Great implementation of the CommentNode! One small suggestion for optimization:

func (c CommentNode) RenderTo(builder *strings.Builder) {
	builder.WriteString("<!-- ")
	builder.WriteString(string(c))
	builder.WriteString(" -->")
}

Thanks for this performance tip. Fixed.

Then we can follow the same pattern as the Element.Render:

func (c CommentNode) Render() string {
	var builder strings.Builder
	c.RenderTo(&builder)
	return builder.String()
}

Fixed.

Looks great, thanks!
