The instructions per account are collapsed by default and expandable in clients that support ui: (like recent Yelp versions). This requires turning the <list> of account types on intro-first-run.page into <section>s as ui:expandable is not supported inside of <list> elements.
Embedding directly does not require users to follow "Click here for configuration instructions for this account" links anymore, that we get rid of "Click here to get to next step if you came from the First Run Wizard help page" sections at the bottom of each account type configuration page.
