## Overview

ARSxedit is a browser-based mobile document scanner. A user grants camera access; the frontend streams frames to Flask for detection and live tracking, sends a frame to capture a warped page, then requests a multi-page PDF or clears the in-memory pages. The graph preserves the documented detection, warp, capture, and export stages. The README describes the UI markup and styling, but the sampled tree’s filenames differ from its documented structure; those assets are included without inferring their wiring.

Main entry points: [`Scanner.js`](https://github.com/arslanansari1629-blip/ars/blob/main/Scanner.js) (Camera and controls), [`app (2).py`](https://github.com/arslanansari1629-blip/ars/blob/main/app%20(2).py) (PDF API), [`index (39).html`](https://github.com/arslanansari1629-blip/ars/blob/main/index%20(39).html) (Scanner UI), [`style (1).css`](https://github.com/arslanansari1629-blip/ars/blob/main/style%20(1).css) (Responsive styling)
