/**
 * Visually-hidden utility.
 *
 * Written from the WAI-ARIA visually-hidden pattern rather than copied from the
 * Joomla source (security rule 2: no executable/stylesheet transfer). Replaces
 * the former theme.update.css, which was byte-identical to
 * templates/yootheme/css/theme.update.css in the frozen -joomla tree.
 *
 * The :not() chain keeps skip-links usable: the element stays hidden until it
 * takes focus, then paints normally.
