/* ========== Player 区域固定比例 640 : 960 (宽:高) ==========
   需求: 中间 Player 保持 640 * 960 的比例 (宽度640，高度960，即 aspect-ratio: 640 / 960 = 2/3 ≈ 0.6667)
   并且尽可能占满页面的高，可留白左右。布局思路：基于高度优先原则，使用 aspect-ratio 锁定比例，
   同时让播放器高度尽可能占满父容器高度，宽度自适应，且最大宽度不超过视口宽度减去左右安全空间，
   保证不会溢出，且完美居中。

   设计核心：
   播放器外层 .player-wrapper 使用绝对定位铺满全屏 + flex 居中。
   内部 .player-inner 设定:
       height: 100%;               // 优先占满父容器高度（尽可能高）
       width: auto;                // 宽度根据比例自动计算
       aspect-ratio: 640 / 960;   // 强制执行 640:960 比例 (宽:高)
       max-width: 100%;           // 防止宽度超出屏幕，造成水平滚动条
       当高度100%时，宽度自动 = 高度 * (640/960)。如果计算出的宽度超出父容器宽度(max-width:100%生效)，
       则宽度被限制为100%，高度会按比例收缩，保持比例完整。
       在宽屏或普通屏幕下，只要视口宽高比 > 640/960，高度始终占满100%；而视口比例小于比例时宽度受限，
       高度不满，但此时左右留白更多。但这是保证「尽可能占满高度」与「比例不变」的最佳实现，
       完全符合需求描述。
       此外针对竖屏需求（手机竖屏或高窗口），大多场合高度占满，左右留白优雅。
