 * A line said once and gone, in the playlists' note (style.css

 * nothing here is anyone's to dismiss.
 *
 * Appended to the body rather than rendered by a view, because the views that
 * speak include modals and a context menu that has already closed. One note
 * at a time: a second replaces the first and restarts the clock.
