 * 移动端适配
 * -------------------------------------------------------------
 * 1) 视口高度：手机浏览器的地址栏会占掉一块，100vh 取的是「地址栏收起」
 *    时的高度，于是底部播放条那一行被顶到可视区外；而 html/body 是
 *    overflow:hidden 的，用户也没法滚下去看。改用 dvh 后播放条始终可见，
 *    并给全面屏留出底部安全区。
 * 2) 侧边栏：≤860px 时原来的规则直接 display:none，手机上没有导航入口。
 *    这里改成可滑出的抽屉 + 遮罩，由工具栏的汉堡按钮控制。
