• Local AI Vision: Uses BLIP/GIT models via transformers to generate alt-text for free.
• CORS Enabled: Configured to communicate with the Vercel frontend.
• Automatic Remediation: Fixes color contrast and missing titles.

🛠 Tech Stack

• Language: Python 3.10+
• Framework: FastAPI
• Libraries: python-pptx, torch, transformers, lxml
• Deployment: Docker on Hugging Face Spaces

🚀 How to use

The frontend (deployed on Vercel) sends requests to this Space's endpoint.

1. Install dependencies: pip install -r requirements.txt
2. Run the server: python app.py
