 本机方案存 config.json 的决定予以保留：这是设备个体偏好，不增加服务端配置或同步通道。通知/作业/叫人使用同一个 IslandApp.vue 实例及原状态机，custom 模式仅通过 Teleport 把它放到组件槽；不是固定层盖在自定义层上，也没有第二个岛窗口。主要行禁用提醒时回落到允许提醒的第一行；全部禁用时不展示提醒槽。多种内容仍服从原队列/列表规则，不会在多个位置重复投递。
 
+## 自定义灵动岛界面重写
+
+按后续反馈，将组件栏明确收进同一个岛体：普通组件和提醒共用外层背景、圆角与阴影，嵌入提醒只保留原渲染器的内容、动画与操作，去掉原卡片的第二层背景形状。每行的普通组件与提醒上下排布，岛宽取两者中较宽的一项，避免横向累加造成留白。没有消息的通知、作业、叫人组件不占位。固定模式继续使用原有完整卡片。
+
+编辑界面重写为左侧组件库、中央岛内预览、右侧当前对象设置。组件库按日常信息、消息提醒、组合容器分组，采用统一 SVG 线性图标；组件设置分为内容、外观、高级三个标签，独立外观关闭时禁用覆盖项。行名称、间距、主要行和通知开关放在行设置中，整体配色、缩放和多行选项放在整体外观中；方案复制与导入导出收在顶部菜单。
+
+主设置页以两个选项选择经典或自定义灵动岛，自定义模式直接进入「编辑岛内组件」，隐藏不适用的固定宽高等选项。退出全屏编辑时，先在隐藏期间等待常态组件重新测量，避免保留行工具栏的空白高度；自然宽度测量也不再被上一轮获准窗口宽度撑住。分离多行时按实际外层留白计算尺寸。
+
+新增回归检查设置标签隔离、共用岛体且无第二层形状、无消息不占位，以及退出编辑后的自然内容尺寸；关闭提醒通过原渲染器的「知道了」按钮验证。最终截图留档在 `.cache/island-rewrite-final-shots/`。
+
+本轮视觉回归通过 102/102，随后补充的岛宽修正与展开可见性检查通过后台 28/28，并通过二次启动。后台最终几何检查先等待原渲染器的形变兜底和尺寸防抖完成，避免在隐藏窗口的中间动画帧判断最终尺寸。客户端构建、类型检查、lint、改动文件格式检查及文档严格构建均通过。
