This is for ComfyUI-Easy-Use and its 'easy stylesSelector' node.
Put the folder grok_samples and the file grok_styles.jason here:
...\custom_nodes\comfyui-easy-use\styles
The zip also contains a workflow easy-use_style-example-workflow.json that shows a basic switch between prompt and prompt+style.
This is meant as an easy to understand example that you can use to make your own styles or just use it as an addition to the built-in fooocus styles.
(I used Grok to generate the different styles hence the folder/file name.)
