 * DOM 結構分析：
 * - header.php 有 <main id="primary" class="site-main">
 * - my-account.php 直接輸出 <div class="account-page">，沒有被 .container 包裹
 * - 但 WooCommerce My Account 頁面在 WordPress 中仍然是一個 Page，可能被頁面模板包裹
 * 
 * 真正限制寬度的 selector：
 * - .container 的 max-width: 1120px (全局，第 34 行)
 * - 如果 My Account 內容被包在 .container 內，就會被限制在 1120px
 * 
 * 解決方案：針對 .woocommerce-account 頁面，放寬所有可能的 .container 寬度
