I think a plugin should contain 1 asset file and not separate ones for each feature? Unless Filament has a CSS/JS merge function for production, to reduce the number of files and therefore HTTP requests?
With Sass and Less CSS preprocessors, one can still separate component CSS/JS into own files and then import them into a top-level file. But I think we are not using them here?
