I can't find justifications for going beyond App -> Page -> Components, and introduce lower levels. You can rule out Atoms as layer if you work with a style guide and define them globally at the app level. You'd override or modify "Atoms" values at the component level if you need to. Even just a word or text can be regarded as component if you include the surrounding whitespace. Whitespace matters! The conclusion is that the highest and lowest levels are actually the same! You build your components from the global style guide/CSS stylesheet!
