### 🚑 其他信息

The issue names the Watermark component and the runtime layout function in app.tsx; begin by clarifying the intended global scope and how that layout is configured. A usable resolution should include a reproducible example and an explicit expected result, since the current report contains no example code or acceptance criteria.
