How do styles and scripts interact in BEMjson?

Question

JavaScript

I have been writing combat projects on BEM-naming for a very long time. Recently it was advised to start using BEM full stack with the bemjson templating engine and enb. I smoke Yandex manuals and it seems to be clear, but I'm missing one point.
Did I understand the logic correctly?
There is desktop.bundles. It stores page templates in json format.
There is desktop.blocks. Blocks and their elements are stored there. More precisely their javascript and css.
I created the page, wrote the simplest header markup. In desktop.blocks I created a header, put header.styl there.
In the page, I connected header.css, which, in theory, should fall to my desktop.bundles. But for some reason it doesn't compile or crash. Although in .enb/make.js the enb-stylus configuration is definitely correct. There are no errors in the console. Also, enb says:
17:16:18.369 - build finished - 121ms
----- /desktop.bundles/page/page.html 134ms
17:16:18.426 - build started
17:16:18.435 - build finished - 12ms
----- / desktop.bundles/page/header.css 12ms
But /desktop.bundles/page/header.css is not in the result. It is not created. Error /desktop.bundles/page/header.css 404 not found in the browser console.
Help me understand - how to correctly connect styles and scripts to the page in bemjson?

I think they will answer you here faster, many people use BEM, but the full stack is much less.
