sz3/libcimbar — reverse-engineered prompt

Build me a working file transfer tool that sends data between devices without wifi, bluetooth, or cables by showing an animated color barcode on one screen and decoding it back into the original file from captured image frames. I want the core command line flow to work on Linux, so I can encode a file into a series of images or a live animated window, then decode those images back into the file even if some frames are missing or out of order. Please include compression and error correction so it is practical for real use, and keep support for reasonably large files, around the size this project already targets.

If this repo already has a browser based encoder, keep that working too so it can run offline in a modern browser. Make the build and usage straightforward, with clear commands and sensible output paths. If tests or sample files make sense, add them. You can check current docs online if you need to, but please stick to what this project is already meant to do.
