/* ============================================================
   修正：详情页 .pd-item-body 是 flex + order 布局。
   原 CSS 用 .pd-item-h2{order:6} / .pd-spec{order:7}，
   但详情页有两个 h2（SPECIFICATION / AVAILABLE COLOURWAYS），
   第二个 h2 拿到 order:6 会排在 .pd-spec(order:7) 之后 → 标题跑到表格下面。
   解法：用 nth-of-type 递增给同类型兄弟排唯一 order。
   阅读顺序：eyebrow → h1 → mat → desc → bs-meta → H2 → spec → H2 → colors → fine → act
