That would hold true for whatever systems. The pretention is just for making it easier to do the job without extraneous effort. Cascading is a nice pattern for applying properties in the case of a document. JS was originally intended for scripting (not for full-blown application) and the DOM API works fine for that. Without that, we would have to put everything in HTML or have something like Flash.

Remember how you started with how every UI system and framework was somehow this separtaion of style and presentation and structure and interactivity?

And now it's "they are never separated, and this holds true for whatever systems"

In reality there's a lot of extraneous effort especially when systems become more complex. BEM was invented not because CSS was great and amazing at reducing effort, but because it was adding a great amount of effort for a very large number of designs.

CSS Scoping was finally, thankfully, added not because cascading nature of CSS reduces a lot of effort.

The rest of your comment has nothing to do with what I said.

What I described as separation is a a decomposition into modules which are linked together through a contract. CSS has cascading and selectors, while JS has the DOM API. Otherwise, it would still be attributes on tags.

BEM is just a development technique, not a technical requirement or capability. Without cascading, we would probably have components and inheritance.

On Android and iOS, you have XML for layout. QT and GTK have support for CSS like styles. I remember at least one of the have supported XML for layout definition. They're not required, but they make it easier to build the UI as it almost always have a tree structure.

Those systems have support, but there's rarely, if ever, a true separation of styling and structure. There's a reason for that, illustrated here: https://x.com/simonswiss/status/1664736786671869952 The separation between CSS and HTML is a good idea in a very theoretical abstract academic sense. It never ever worked in practice.
