/* 20260505 共用 lightbox 播放器（從 post2.html <style> 抽出，供 view / view_category / 等其他頁面共用）
 * 設計脈絡：
 *  - hls.js + media-chrome 引擎（取代舊版 video.js + videojs-contrib-hls + dynamic-watermark plugin）
 *  - 主題：質感灰玻璃 + 2-row 留呼吸 + 個別控制鈕圓角膠囊底
 *  - lightbox 級 fullscreen（包含 thumb-strip / counter / toolbar）而非 native video fullscreen
 *  - has-thumbs 桌機 translateX(-130) / 手機 translateY(-90) 抵銷與按鈕反向修正規則
 *  - idle 5s 自動隱藏右上工具列 + 左右切片鈕
 *  - 容器寬度感知 narrow-thumbs（fullscreen / split-view 等情境用 ResizeObserver 而非 viewport @media）
 * 詳細決策見 git commit 569f13b、3e5f2b9、e5701c1、c457688、da0e1a1 等多輪迭代
