# W-011 Status

status: done
task: 建立应用布局和状态层

## Evidence

- App shell: `web/app/src/app/App.tsx`
- UI styles: `web/app/src/app/app-shell.css`
- Entry point: `web/app/src/main.tsx`
- Screenshot: `tests/golden/W-011/layout-1440x900.png`

The first shell includes Blender-style Topbar, Workspace tabs, Viewport,
Outliner, Properties, Timeline and StatusBar. Workspace selection and timeline
frame state are local UI state; no geometry arrays are stored in React state.
