   COSMOX Pro — WooCommerce Blocks 樣式層
   --------------------------------------------------------------------------
   為什麼需要這一層：
   本站的「購物車 / 結帳」頁面使用 WooCommerce 的 Gutenberg 區塊
   （woocommerce/cart、woocommerce/checkout），其 DOM 由 React 在前端產生，
   標記與傳統 [woocommerce_cart] 短碼完全不同，因此 assets/css/woo.css
   內針對 .woocommerce-cart-form / table.shop_table 的規則不會生效。
   本檔案補齊區塊版本的視覺，使其與主題的「深林綠 × 香檳金」語言一致。

   載入時機：僅在購物車 / 結帳 / 訂單相關頁面（見 inc/assets.php）
   索引：
