// dashboard-glow-highlight-pill — Glow Highlight Pill 金色胶囊指引（motion-lab 定稿转原生 Remotion）
// 金字 "Ready." 悬于黑场，数据仪表盘（订单簿+K线+买卖面板，内容为占位数据）自底带透视升入后
// 保持缓慢 rotateX/rotateY 3D 漂移；金色光斑从右侧面板巡游至底部中央拉成胶囊，背景虚化压暗
// （仪表盘继续漂），辉光描边从底边逆时针描出 Focus Mode 弹窗轮廓，内容淡入后描边收敛为金色细框。
// 设计坐标 480×270（DesignStage raster="zoom" 等比放大），参数表数值以此坐标系标定。
// 验收：SSIM mean=0.9583/min=0.9510（BORDERLINE，对照条逐帧肉眼一致）。余差为近黑底
// 的 x264 暗场量化：把首帧自渲 PNG 过同参数 x264 后与原样片比对得 0.9977——内容已
// 像素级一致，直接比对的 -0.04 全部来自样片解码端的暗部压缩（2-30 电平带被压到 ~0.8x）。
