/*
 * Reverb admin navigation icon
 *
 * The <i class="reverb-nav-icon"> is rendered by OC3 AdminLTE sidebar.
 * CSS mask lets the SVG shape act as a clipping mask over background-color,
 * so the icon inherits currentColor and matches whatever the sidebar text
 * colour is (white on hover/active, 75% white when inactive).
