			/*

			Based off glamor's StyleSheet, thanks Sunil ❤️

			high performance StyleSheet for css-in-js systems

			- uses multiple style tags behind the scenes for millions of rules
			- uses `insertRule` for appending in production for much faster performance

			// usage

			import { StyleSheet } from '@emotion/sheet'

			let styleSheet = new StyleSheet({ key: '', container: document.head })

			styleSheet.insert('#box { border: 1px solid red; }')
			- appends a css rule into the stylesheet

			styleSheet.flush()
			- empties the stylesheet of all its contents
