/**
 * Wakasm shared modal component.
 *
 * Standardized modal chrome for site-wide use. Mirrors the sticker designer
 * modal style (dark overlay, dark dialog) so existing modals can migrate
 * onto this without visual change.
 *
 * Markup contract:
 *   <div class="wakasm-modal" hidden role="dialog" aria-modal="true" aria-labelledby="...">
 *     <div class="wakasm-modal__backdrop" data-modal-close></div>
 *     <div class="wakasm-modal__dialog">
 *       <header class="wakasm-modal__header">
 *         <h2 class="wakasm-modal__title" id="...">Title</h2>
 *         <button class="wakasm-modal__close" data-modal-close aria-label="Close">×</button>
 *       </header>
 *       <div class="wakasm-modal__body">…content…</div>
 *     </div>
 *   </div>
 *
 * JS (wakasm-modal.js) handles open/close via [data-modal-open="<id>"] and
 * [data-modal-close], plus ESC-to-close.
