+	User does not load the partial, as the component will. 
+	This allows to overwrite some SEO object keys with project's own.
+	Project's partial should live under `layouts/partials/seo/extend.html`

+		{{- if eq "Type" "recipe" -}}
+		{{- .Scratch.SetInMap "seo" "type" "article" -}}
+		{{- end -}}
