@mburridge (or anyone else that wants to give their opinion) quick check: does
state.yoast.onlyInSSR sounds right in English?
This is a setting for the
@frontity/yoast package, that adds the head tags generated by Yoast only to the server side rendered HTML (but not to the client rendering). It’s for performance reasons, although it’s deactivated by default.
It could be other things like
state.yoast.rendering: "server"… Or even mention the client if that makes more sense:
state.yoast.skipCSR and so on…
