Get your beauty sleep. Get plenty of sleep nightly. Itâs not entirely clear why inadequate sleep results in dark circles under the eyes, but lack of sleep tends to cause the skin to become paler (thus increasing the appearance of darkness under the eyes), and reduces circulation. Itâs also believed that too little time lying down is a cause in itself.
Style Library is located on the top level publishing web site. So you need to enable the publishing feature on the root site as well.
You should reconsider this design. SharePoint is not built to handle this amount of folders with unique role assignments in one document library. I would recommend that you take a look at a design where you instead of using folders use Site Collections/Sites/Document Libraries as your hierarchy.
