 * excluded from the lftp deploy via --exclude-glob='_template/'). If this
 * file lived there it would never reach the live server, and every shop page
 * (which references /shop/shop.css) would render unstyled. It must live at
 * the deployed path /shop/shop.css.
 *
 * Tokens mirror the parent home (/index.html). If the parent's CSS custom
 * properties change, mirror the change here.
