/* ==== 加倍弹层：强制居中 + 背景只模糊不变暗（2026-10-08 用户要求）====
 * ① 遮罩：.overlay 默认 background: rgba(0,0,0,.55) 会把整桌压暗。
 *    这里换成**几乎透明的黑 + 更强的 backdrop 模糊** —— 毛玻璃感，
 *    桌面的绿绒与牌面都还看得清，只是被"推到后面"，且不牺牲亮度。
 *    backdrop-filter 不生效的环境（老 WebView）靠 rgba 的 alpha 兜底也不会全黑。
 * ② 居中：竖屏靠 .overlay 自带的 align-items:center；
 *    横屏 @media 里 .overlay:not(#overlay-bidding) 被改成 align-items:flex-start，
 *    居中依赖 `> .panel { margin: auto; }` —— 而加倍面板的类名是
 *    **.double-panel 不是 .panel**，没吃到那条规则 → 横屏下贴顶（截图即此症状）。
 *    这里对 .double-panel 显式给 margin:auto，两种朝向都真正居中。
