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.

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.
For #1: The maximum library limit is 30,000,000 documents. The maximum practical limit for a single folder is 2000 files. Sharepoint does not scale well beyond 1000 files per folder. For #2: There's no practical limit for the number of subfolders. Your folder structure will become unmanageable well before you reach the limit. The complete URL for the file or folder cannot be longer than 260 characters.
