Three critical fixes to resolve AI extraction returning null prices with 0.0 confidence:
1. **Add French price/stock keywords** (app/utils/text.py)
- Added € symbol and French price patterns (12,99 €, 1 234,56 €)
- Added French keywords: prix, coût, promotion, réduction
- Added French stock keywords: ajouter au panier, en stock, rupture, épuisé
- Previously only detected $ and English keywords
2. **Enable full-page screenshots** (app/services/browserless_service.py)
- Changed full_page=False to full_page=True
- Now captures entire page instead of viewport-only
- Prevents missing prices located below the fold
3. **Increase image resolution** (app/utils/image.py)
- Increased MAX_IMAGE_SIZE from 1024px to 2048px
- Preserves fine details in price text for better AI recognition
- Improves readability on dense product pages
These changes fix the issue where AI models returned:
{"price": null, "price_confidence": 0.0, "in_stock": null, "in_stock_confidence": 0.0}
Tested with Amazon.fr product monitoring.
