 Python Environments
 ===================
 
-DataFog currently declares support for Python ``>=3.10,<3.14``. The CI matrix
-tests core, NLP, and NLP-advanced installs on Python 3.10, 3.11, 3.12, and
-3.13. OCR profile smoke checks also run on Python 3.13 with system Tesseract
-installed. Distributed and all-profile installs remain heavier optional
-profiles rather than the lightweight core support claim.
