It's designed to allow people to explore in an offline mode - especially if we wanted to allow users to explore benefits mapping as a blog post, without signing up to the "full" tool.
This approach can be used more for the "learning a technique" type of guide.
To support this we would provide lots of controls here, for example removing access to the menu bar, or keeping the user in read-only mode.
We also want to only bother loading everything when the document is needed, so we wait for the user to activate the document before starting.
It's currently using the same document, so shouldn't do anything different - but eventually we'll have different examples and probably place this all on our website.
