I don't think the javascript part is future-proof. Any client side UI rendering logic is tightly integrated with browsers' rendering quirks..

That's true, although to some degree the separation of semantics from styling in HTML/CSS/JS means that the structure of the document will be preserved. And at least HTML is a text format! How much can you recover from a proprietary binary format, when the app's not around any more? At best somebody has to reverse engineer it, and it could change in all sorts of undocumented ways between versions of the app.
