(function() {
	'use strict';
	
	var greasemonkeyInterval = setInterval(greasemonkey, 200);

	function greasemonkey() {
		const header = document.getElementsByClassName('header-dark');

		if (header.length){
			header[0].classList.remove('header-dark');
			clearInterval(greasemonkeyInterval);
		}
	}
})();
