/**
 * ★ 播放页打开时，提示条从「底部居中」改到「顶部居中、工具栏之下」。
 *
 * 为什么必须改（四视口逐个求交的实测值，不是估计）：
 *   播放页的按钮栏就在底部，而提示条原本也钉在底部、z-index 200 高于 #stage 的 100
 *   → 提示条直接压住按钮：
 *     · 1440×900  压住 视频全屏 / 画中画 / 截图 / 弹幕开关，冲突 8316 px²
 *     · 390×844   一次压住 6 个按钮（音质·音效 / 原声 / 定时关闭 / 视频全屏 / 画中画 / 截图），冲突 11058 px²
 *     · 1180×900 / 768×1024  刚好错开，冲突 0
 *   挪到「工具栏之下、水平居中」后，这四个视口冲突面积**全部为 0**，
 *   且不遮视频画面（视频在内容区中部，顶部这段是空的）。
 *
 * ★ 落点必须用 --stage-top-h（工具栏实测高度）而不是写死的数值：
 *   工具栏高度随宽度变 —— 1180/1440/768 实测 68px，手机 390 实测 93px。
 *   写死 68 会让手机上的提示条被工具栏压住 25px。
 *   该变量由 player.js 的 syncStageMetrics() 在开播与 resize 时写入。
