+## 常驻岛界面与动画重写
+
+按用户反馈重新读取上游 `ClassicTheme/Styles.axaml`、`Controls/MainWindowLine.cs` 与 `Controls/MainWindowLine.axaml`。
+上游背景宽度过渡为 550ms、`cubic-bezier(0,1,.5,1.1)`，内容使用 200ms 的 SineEaseIn 淡入；行高 40、左右留白 12。
+本产品需要可交互的通知列表和独立空闲展开页，沿用这些度量、背景曲线与内容淡入，展开页高度也使用同一背景曲线。
+
+旧问题由三个因素叠加：内嵌提醒仍播放 WinIsland 胶囊弹簧，外层 ResizeObserver 把动画中间帧当成自然尺寸，渲染端与主进程各延迟 120ms 调整窗口；外壳 `overflow:auto` 在两端不同步时出现滚动条。
+新 `ResidentIsland.vue` 独立渲染常驻内容、空闲页和通知列表，保留既有的消息去重、排序、读回执及按钮动作。
+经典渲染器保留挂载和心跳，但在常驻模式停止弹簧循环、兜底定时器和命中上报，不再内嵌到常驻岛。
+
+常驻窗口使用受工作区限制的固定画布，开合不调用逐帧 setBounds，也不再隐藏 320ms 后重新显示。
+两页内容按各自未变形的 offsetWidth/offsetHeight 测量，保持自己的排版和缩放；只让一个岛壳过渡尺寸。
+内容自然尺寸、配置缩放、字体加载和窗口 resize 决定目标尺寸。长文字先限制宽度并省略，时间、分隔线和文字成组对齐；多行布局整体适配可用宽高。
+消息正文限制可见行数，按高度限制列表数量，剩余内容由应用内入口承接；底部动作不被正文挤出，运行界面没有滚动容器。
+
+原生窗口的 show/hide 通过专用白名单桥同步到渲染器；不可见时直接应用目标几何，避免后台 CSS 动画冻结在中间帧。
+命中矩形仅在动画期间每 60ms 限流上报，结束时补报；静止时没有动画采样循环。
+开合期间暂停指针淡化，避免鼠标留在旧展开区域时因过期命中矩形误触发 5% 透明度，造成收起闪烁。
+Windows 触摸模式使用 Electron setShape：动画开始放开绘制区域，完成后只保留岛体及 8px 投影留白的原生区域，透明画布不再长期吞掉周围桌面输入。进入编辑、关闭常驻或关闭触摸模式时清除区域。
+
+新增回归覆盖开合窗口矩形恒定、动画帧间隔、所有运行节点无滚动容器、360×260 窄画布与 2.5 倍缩放、底部右侧停靠、长正文及多通知底部动作、触摸输入区域收敛。测试保持隔离配置与本地通知，不连接真实班级。
+
+本轮视觉验收 123/123，通过连续快速开合与停靠命中检查；1.8 秒取得 109 个动画采样，帧间隔 P95 为 16.8ms，原生窗口矩形只有 1 个。
+最终补充收起期间错误淡化的回归后，后台检查 49/49；桌面类型检查、全仓 lint、构建及产物凭据门禁、格式和文档严格构建通过。
+视觉记录与截图为 `.cache/resident-rewrite-final-visual.json`、`.cache/resident-rewrite-final-shots/`，最终构建后台记录为 `.cache/resident-rewrite-delivery-quick.json`。

 没有待处理消息时点击岛体，展示自定义的空闲展开页；处理完消息后回到常驻内容。关闭常驻后使用原提醒规则。
 铃铛在右侧预留固定空间，收到消息时内容不横移；默认组件按垂直中心对齐，时间使用等宽数字。
 常驻外观重新按 ClassIsland 源码对齐：单行基准高 40 px、左右留白 12 px、四档字号 14/16/18/20、时钟使用强调字号 18 px；默认缩放 1×、圆角 8 px、背景不透明度 0.5、行间距 5 px。
 窗口设置沿用「指针移入淡化」与「反转指针移入淡化」；普通背景淡化至 5% 并穿透点击，移出恢复。铃铛/展开按钮、编辑模式、已经展开的内容及触摸操作短暂宽限期保持可交互。

+常驻岛独立使用 ClassIsland 经典主题的 550ms 背景尺寸曲线与 200ms 内容淡入；旧胶囊弹簧在常驻模式停止运行。
+开合只改变岛壳，原生窗口保持固定画布，避免窗口重排、闪烁和两端尺寸防抖互相追赶。隐藏窗口直接落到目标尺寸。
+布局按内容自然尺寸、屏幕可用空间和缩放设置自动适配；长文本限制宽度并省略，同一行的时间、分隔线与文字保持成组对齐，左右及底部停靠保持对应锚点。
+通知列表和空闲展开页均不出现滚动条；较多消息按可用高度展示，完整长正文及剩余消息可通过「查看完整内容」进入应用查看，底部操作始终保留。
 编辑器左侧按用途添加组件、中央预览岛内排列、右侧只显示当前对象的设置；方案操作收在顶部菜单。
 主设置页选择经典或自定义灵动岛，自定义模式的组件尺寸、配色在编辑器中调整，主设置页保留位置与提醒选项。
 迁移保留旧 Schedule 作为审计来源；新门面只写新模型。重复占用同一时间点的旧行无法同时成为一节课，
