Hey @GemmaLouise, I think these are all done from a design point of view. The unlinked ones are using existing tokens (I think all the wrappers etc are just using the text tokens).

I added in an example of the PageIntro but this is mostly made of other components that are already complete, the onyl exception is the background of the description list section which i've added in the background-information color token. They are as accurate build wise as I have time for so should be alright given the upcoming review of components anyway.

Cheers, Kyle
