  品牌渐变 + 深色滚动条
- shell: TopBar(品牌渐变+毛玻璃+发光健康灯) / LeftNav(激活态紫色高亮+左光条) /
  BottomDrawer(深色+状态色)
- 新 views/Home 工作台仪表盘: 渐变 hero + 4 状态卡 + 3 能力卡 + 快速开始(默认首页)
- 画布: TypedNode 深色节点卡; StudioView ReactFlow colorMode=dark + 深色工具栏/面板/
  MiniMap; Inspector 深色表单
- KbView/MemoryView/MemoryPanel/Placeholder 全深色化; 进度条改紫青渐变
- 纯前端改造, npm build✓; 浏览器验证: 仪表盘 + 编排画布深色呈现
