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).
