/* ---------- ⑤ 区块之间的辅助图形点缀 ----------
   ★★ 2026-10-03 修：这一块上一版做坏了 ——
      原来写的是 width:100% + max-height:190px + object-fit:cover，
      可这张底纹是**方形的**（622×540）。强行按 100% 宽去铺、再用 cover 裁到 190px 高，
      等于把它**横着"切"掉上下两头**：七七截图里"头尾全被切没、还拉满整屏"就是这个原因。
      （七七原话：这太大太丑，不行就不放了吧。）
      现在改对：**按原始比例、给它一个固定小尺寸、低透明度**，
      只当区块之间一个淡淡的小点缀，不再抢戏。
