PrismOCR: Deterministic Computer Vision for Label Extraction

A production-ready OCR engine that extracts structured product label data (GTIN, FSSAI, net weight, MRP, dates, and more) using barcode decoding and deterministic computer-vision rules, with validator-gated accuracy and zero data fabrication. There is no LLM involved: this is pure computer vision, running entirely offline with zero per-document API cost.
