## TL;DR
```bash
cd /home/node/.openclaw/workspace/skills/xeonupscale
./upscale.sh in.mp4 540p                       # → in_960x540.mp4
./upscale.sh in.mp4 1080p out.mp4
./upscale.sh in.mp4 1920x1080                  # 自定义分辨率
```

"syntax OK": `540p` / `720p` / `1080p` / `1440p` / `2160p|4k`，或直接 `WxH`。
