create_site — Create a whoisbrowsing site
Creates a whoisbrowsing site with no sign-up and returns its script tag (snippet), one watch link per website, a one-time claim link, a terms sentence for the human and the next steps. Call it once per project; one site can hold several domains. Never write the watch or claim link into a file, commit or log.

}check_live — Is the script connected right now?
Asks the live server whether the site's script is connected right now: the websites with a visitor, how many visitors, and which websites the owner is watching. Needs the site's owner key, the part after #wib= in the watch link create_site returned. Load a page that has the tag before calling it: a tab other than the owner view (it shows up as "you, testing"), or a fresh browser context.
