1. 首页数据不刷新 — JournalRepository 添加 onJournalChanged Stream 变更通知，HomeBloc 订阅后自动刷新 2. 画笔再次点击不弹出面板 — 添加 ToolReactivated 事件， 工具栏检测已激活工具时发出重新激活信号 3. 钢笔铅笔效果一样 — 调整 perfect_freehand 参数 (pen: size 10/smooth 0.65, pencil: size 3/smooth 0.35) 4. 橡皮擦不生效 — ActiveStrokePainter 橡皮擦模式绘制 半透明灰色反馈，笔画完成后 setState 触发 Layer 1 重绘 5. 贴纸文字无法缩放 — DraggableElement 用 Scale 手势 替换 Pan 手势，支持双指缩放和旋转

// 手账编辑器页面 — 三层 Stack 架构
|
||
//
|
||
// Layer 1 (底层): HandwritingCanvas — 手写画布
|
||
// Layer 2 (中层): DraggableElements — 贴纸/照片/文字元素
|
||
// Layer 3 (顶层): EditorToolbar — 底部工具栏 + 顶栏操作
|
||
//
|

// 交互逻辑：
|

// - 画笔模式 → Layer 1 接收手势，Layer 2 透传
|
||
// - 选择模式 → Layer 2 接收手势，Layer 1 透传
|
||
// - 工具栏 → 始终在最顶层
