It wasn't a style change. The structure of the admin sections changed. We introduced a second admin section called an "account admin" based on new understanding of the abilities of "Blue Sky admins" (kind of like a super admin) and "Account admins".

I passed the account id as a simple way to then save it in a session, to be used as long as the admin is working on that account. I did that to reduce route/controller/view nesting and improve named route readability. An alternative would have been using things like `admin_account_category_path(@account, @category)` which was verbose for my tastes.
