+### Requirements.txt pour HF Spaces
 
-HuggingFace Spaces nécessite un `requirements.txt`. Pour le générer depuis Poetry :
+Le fichier `requirements.txt` est **minimal et optimisé** pour HF Spaces (seulement gradio, huggingface-hub, joblib).
 
+Il est **généré automatiquement** par le CI/CD lors des déploiements.

+Pour le générer manuellement :
 ```bash
