// 组合：命令面板 × 深浅扫场（palette-theme-ripple）
// FakeDashboard 静置 → 整屏压暗+blur → ⌘K 面板弹落 → 模拟输入"dark"
// （灰块字符逐个弹出）→ 回车帧面板 5f 收缩成一个亮点 → 深色扫场边界
// **从该亮点位置**荡开（clip-path 圆扩张 + 亮边缘环）扫过全 UI 变深色版 → 真静止。
// 组合命门：扫场起点必须是面板收缩点（960,470），收缩完成帧=扫场起始帧
// （RIPPLE=73），从别处/别帧开始就断了因果。
// 关键帧：0–15 浅色静置 → 15–22 压暗 blur → 22–30 面板弹落（超调）→
// 38–62 逐字输入 d/a/r/k → 68 回车 → 68–73 面板收缩成亮点 → 73–95 扫场
// 荡开 → 95–170 深色真静止 75f。深色版为手工反转 G 色板的本地 DarkDashboard。
// 帧确定，无随机源。
