# MathSnap Deblur

Sharpens blurry photos of printed math pages for the MathSnap app's preview. It runs NAFNet
(GoPro motion-deblur, width 64) on free ZeroGPU hardware, in 384×384 tiles with feathered seams.

- Endpoint: Gradio API `/deblur` taking `[jpeg_base64, key]`. It returns a base64 JPEG of at most 2048 px.
- Only the MathSnap Supabase function knows the key. Set it as the Space secret `DEBLUR_KEY` (32+ characters).
- Images are processed in memory and are never logged or stored.
