# W-013 Status

status: done
task: 建立 Three.js 视口烟测

## Evidence

- Adapter: `web/app/src/three-adapter/viewport.ts`
- Uses vendored Three.js `0.185.1` from `web/app/src/vendor/three/`,
  `WebGLRenderer`, `Scene`, `PerspectiveCamera`,
  `OrbitControls`, `GridHelper`, lights, resize observer and disposal.
- No runtime CDN request is required; Playwright asserts all requests stay on
  the local dev origin.
- Screenshot: `tests/golden/W-013/three-viewport-1440x900.png`

## Verification

```text
npm run typecheck  # passed
npm run lint       # passed
npm run build      # passed
Chrome headless --use-gl=swiftshader --virtual-time-budget=60000  # rendered cube/grid
```

The renderer failure path is contained in the viewport component, so browsers
without a WebGL context keep the editor shell available.
