Consider replacing e.g. some-component-theme.css with some-component.theme.css.

I wonder if this would be a little clearer, since it makes it a sort of "subdomain" of the main extension rather than just part of the name, clearly separating it as something speical. Would need to ensure it works with e.g. some-block.view.js and some-block.view.css without breaking.
