## 🚀 **OPTIMIZATION RECOMMENDATIONS**

### **Priority 1: Environment Configuration**
```python
# Add to src/config/settings.py
import os

# Environment variable overrides
OLLAMA_BASE_URL = os.getenv('OLLAMA_BASE_URL', 'http://localhost:11434')
OPENAI_API_KEY = os.getenv('OPENAI_API_KEY', 'your-openai-api-key-here')
FIREBASE_PROJECT_ID = os.getenv('FIREBASE_PROJECT_ID', 'styler-24736')
```

### **Priority 2: Version Validation**
```python
# Add to src/main.py check_system_requirements()
def check_python_version():
    if sys.version_info < (3, 7):
        print("❌ Python 3.7+ required")
        return False
    return True
```

### **Priority 3: Enhanced Error Logging**
```python
# Add logging configuration
import logging
logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
    handlers=[
        logging.FileHandler('style_transfer_ai.log'),
        logging.StreamHandler()
    ]
)
```
