/*
 * Shared "concept work" notice bar for every page under /works/.
 * The ONLY file shared between the four concept LPs.
 *
 * Markup (place as the first element inside <body>, before the LP header):
 *
 * <div class="concept-bar" role="note" aria-label="コンセプト制作についてのお知らせ">
 *   <div class="concept-bar__inner">
 *     <p class="concept-bar__text">
 *       <span class="concept-bar__badge">コンセプト制作</span>
 *       これはズオン・クオック・トゥアンによるコンセプト制作（架空のブランド）です。実在の企業・商品・サービスとは関係ありません。
 *     </p>
 *     <a class="concept-bar__back" href="../../#works">← ポートフォリオへ戻る</a>
 *   </div>
 * </div>
 *
 * The bar is in normal flow (not fixed), so it causes no layout shift and
 * never covers the LP's own sticky header. It deliberately uses a neutral
 * palette that belongs to none of the four brands.
