+I have analyzed the current project structure and designed a "Check-in Large Screen" (签到大屏) solution that integrates seamlessly with your existing system.
+
+### **Plan Overview**
+
+I will implement a **"Galaxy Spotlight"** style large screen:
+
+1. **Background (Danmaku/Floating Tags)**:
+
+   * `Business Scope` and short `Vision` keywords will float elegantly in the background like stars or drifting clouds.
+
+   * Uses the project's blue/cyan tech theme.
+
+2. **Foreground (Spotlight Card)**:
+
+   * A central, animated card that cycles through checked-in guests.
+
+   * Displays: **Company Name** (Prominent), **Guest Name/Position**, and **Vision 2026**.
+
+   * Updates every 8-10 seconds to ensure everyone gets exposure.
+
+### **Implementation Steps**
+
+#### 1. Backend (`main.py`)
+
+* Add a new route `/wall` to serve the large screen page.
+
+* Add an API `/api/wall/data` to fetch approved check-in data (filtering out empty entries).
+
+#### 2. Frontend (`templates/wall.html`)
+
+* Create a new responsive HTML template.
+
+* **Visuals**: Reusing the `radial-gradient` background and neon aesthetics from `index.html`.
+
+* **Animation**:
+
+  * JS-based floating animation for background tags.
+
+  * CSS transitions for the central spotlight card.
+
+#### 3. Admin Integration (`templates/admin.html`)
+
+* Add a button "Open Large Screen" (打开签到大屏) in the Admin Dashboard for easy access.
+
+### **Technical Details**
+
+* **Tech Stack**: Native JS/CSS (no extra heavy libraries needed), integrated into the existing FastAPI app.
+
+* **Data Source**: Reads directly from `checkin_info` table.
+
+* **Compatibility**: Optimized for 1080p/4K displays (MacOS standard).
