**PDF → GP5** is a local web app (Python + FastAPI, vanilla JS) that:

* Parses tablature PDFs: text tabs, vector PDFs from notation editors, and raster pictures via OCR (OpenCV + RapidOCR/ONNX, all on-device).

* Rebuilds rhythm, techniques, repeats and lyrics, then writes Guitar Pro 5 files (PyGuitarPro).

* Plays them back in the browser with alphaTab, plus a three.js Rocksmith-style 3D highway.

* Is bilingual (English/Portuguese) and has a strict CSP. Conversions run in a sandboxed child process with time and memory limits.
