So, like combining a few webpages, a la frames? (Not WML cards, but something a bit more…)

Making them really portable means encapsulation, for script and styles. That's what BEM Blocks do in existing HTML, and frames did in the 90s.

Because each frame is a page, it has HTTP transactions, metadata, encapsulation, and so on.

Depends. If you want to scope scripts (so they don't clash with other stuff) you might find it worthwhile to think of markup.

In particular, as Marcos noted, something like iframe.

The key is making nice controllers for iframes, so the UI for flipping through a bunch of things is straightforward. But frames were developed for this 20 years ago - if you don't need an easy declarative framework, bookmarking, etc, you will have open standards to do all this in 1999 - although it might take 15 years to get things like cross-frame messaging, a maybe-as-much-as-half-baked security model, etc.

BEM shows a path toward making a declarative framework on top of this, rather than asking developers to make standard UI components themselves each time.

But I don't see anything actually new here.
