1/**
2 * BlueIron Newsletter — AJAX signup form handler.
3 *
4 * Listens for submit events on any <form class="bi-newsletter-form">,
5 * POSTs the email to /wp-json/blueiron/v1/newsletter-subscribe, and
6 * surfaces the response in a sibling .bi-newsletter-status element.
7 *
8 * Required markup:
9 *   <form class="bi-newsletter-form" data-endpoint="...">
10 *     <input type="email" name="email" required />
11 *     <button type="submit">Subscribe</button>
12 *     <p class="bi-newsletter-status" role="status" aria-live="polite"></p>
13 *   </form>
14 *
15 * The data-endpoint attribute is set by PHP via wp_localize_script so the
16 * REST URL is correct on multisite/staging environments.
