TurkicOCR-SVTRv2-B (Quantized ONNX INT8 Model)

TurkicOCR-SVTRv2-B (INT8) is the dynamically quantized INT8 deployment graph. It delivers ~3.1× memory reduction (from 84.4 MB down to 27.1 MB) and ~2.7× faster CPU throughput (~385 lines/sec) with negligible accuracy degradation (1.93% vs 1.76% CER).
