Meter OCR — Custom Detection + Recognition

Highlights

1. Cross-validate a local Qwen3-VL (vLLM batch) against PaddleOCR: where both agree on a string at a location, that tight box becomes the label.
2. Confidence-gated to 1,098+ exact-match gold rows; oriented bounding boxes for tilted meters.
3. YOLO-OBB detection (reading and serial in one pass) plus fine-tuned PaddleOCR recognition; CPU images-per-second benchmarked before deploy.
