"""Read printed text out of an image — what people usually call OCR.

Traditional OCR (Tesseract, ABBYY, etc.) is a dedicated system trained on
piles of text-image pairs and uses character-level segmentation. We do
the same job here by asking a general-purpose vision-language model to
just *read out loud* what it sees.
