 * Toggle in the top navigation bar that switches between the classic (Tapestry)
 * and the modern (Angular) frontend. Visual mirrors the Angular design: a pill
 * switch with a label to its left. Shown only when the ModernToggleShow flag is on.
 *
 * The anchor inherits "line-height: 75px" from the navbar rule, so the label and
 * the pill are vertically centered against the rest of the top-settings items via
 * vertical-align: middle (the same way the material-icons items are centered).
