Consider changing the behavior so that when the page is opened in the browser from the local disk, then it opens edit mode automatically, but when it's published to someone's website and accessed on the open web (check if the address is http/https), then it's a normal, read-only view expected from most pages.
Of course:
1. there should be a way to override this (a query string param or magic URL fragment) so you can look at it in edit mode, too
2. there should be a blanket exception for certain domains/URL prefixes—defaulting to keepworking.github.io (or <https://keepworking.github.io/nash/>)—so it activates edit mode on that site, too, which means that you personally don't have to do anything special to make the demo work (best if this exception is user-modifiable, so e.g. someone else can get the same behavior if they want without using the trick from #1)
