/**
 * Headless WhatsApp message editor. Enhances a `<textarea>` whose value IS the
 * WhatsApp markup you send (`*bold*`, `_italic_`, …). Wires a formatting toolbar
 * and keyboard shortcuts that wrap/unwrap the selection, an optional emoji
 * picker (same `renderPicker` plugin contract as `textarea-emoji`), a character
 * counter, and a live, safely-escaped preview. It applies no visual styles.
 *
 * Markup:
 * ```html
 * <div data-c42-whatsapp-editor>
 *   <div data-c42-wa-toolbar>
 *     <button data-c42-wa-command="bold" aria-label="Bold"><b>B</b></button>
 *     <button data-c42-wa-command="italic" aria-label="Italic"><i>I</i></button>
 *     <button data-c42-wa-command="strikethrough" aria-label="Strikethrough">S</button>
 *     <button data-c42-wa-command="monospace" aria-label="Monospace">{}</button>
 *     <button data-c42-wa-command="blockquote" aria-label="Quote">&gt;</button>
 *     <button data-c42-wa-command="bullet" aria-label="Bulleted list">•</button>
 *     <button data-c42-wa-command="ordered" aria-label="Numbered list">1.</button>
 *     <button data-c42-wa-command="clear" aria-label="Clear formatting">⌫</button>
 *   </div>
 *   <textarea data-c42-wa-input></textarea>
 *   <div class="c42-whatsapp-editor-footer">
 *     <span data-c42-wa-counter></span>
 *     <span class="c42-whatsapp-editor-emoji">
 *       <button data-c42-wa-trigger aria-label="Emoji">🙂</button>
 *       <div data-c42-wa-picker hidden></div>
 *     </span>
 *   </div>
 *   <div data-c42-wa-preview aria-live="polite"></div>
 * </div>
