2 * Currency Switcher for WooCommerce – Frontend JS
3 *
4 * Handles currency selection via dropdown or inline list.
5 * Modes (from localized switchingMethod):
6 *   ajax         — POST to set currency (REST preferred; admin-ajax fallback), then reload without fmecs_* query args.
7 *   query_string — add fmecs_currency to URL and navigate (CurrencyEngine reads GET).
8 *
9 * Localized object: fmecs_localized_data { ajaxUrl, setCurrencyUrl, nonce, switchingMethod }
