## 生成方式

Platform Skill: `playcraft-image-generation`

```bash
# 1. 生成图片（参考 ref/ 中的参考图）
playcraft tools generate-image \
     --prompt "vast desert landscape, golden sand dunes, clear blue sky, casual mobile game style, flat design, warm colors" \
     --aspect-ratio 9:16 \
     --image-model google/imagen-3.0-generate-002 \
     --output ta-workspace/raw.png

# 2. 后处理（去白底 + 格式转换）
playcraft image remove-background --input ta-workspace/raw.png --output ta-workspace/trimmed.png
playcraft image convert --input ta-workspace/trimmed.png --output ta-workspace/background.webp --quality 85

# 3. 将产物写入 sandbox 对应路径（见 binding.target）
```
