/*
 * The appearance switcher (E2-11): a toggle button and a popover menu with the scheme,
 * palette and style. Every site renders the same markup with its own strings; /shared/prefs.js
 * handles the buttons. This file is copied to the portfolio by `npm run sync:shared`.
 *
 * Set --prefs-top on the page to place the menu under its header.
 *
 * The language button (E2-12) sits next to the toggle and shows the other language's code.
