I was  just intending to show the structure of the script tag that is needed, 
but as it happens one could include such a script tag directly in a 
$:/tags/RawMarkup tiddler.

No, you could load them on the fly: clicking a button would trigger the 
tm-load-jsonp message, which would then load the tiddlers dynamically.

Browsers have, until recently, been relatively laissez fair about continuing 
with the features that web developers need for testing simple web pages locally 
via a file:// URI. Just recently, though, new features (like service workers) 
are restricted in such a way that a local web server is required for 
development.

(By the way, the reason why loading code is safer than data in this context is 
because JSONP can only be used to read files that (a) one knows the URL and (b) 
the file contains valid JavaScript that returns a result in a very specific 
way. Note that the invoking JavaScript code never sees the literal content of 
file that is loaded, it just sees the results of executing it. So it’s pretty 
much impossible to use this technique to exfiltrate personal data, whereas a 
generic capability to read data files where one knows the path would be 
absolutely devastating).

Best wishes

Jerwemy.
