select_option()      # Select from options
validate_hf_token()  # Validate HF token

# Configuration
show_training_configs()    # Display available configs
get_training_config()      # Get config based on selection
create_training_config()   # Generate config file

# Output formatting
print_status()       # Success messages
print_warning()      # Warning messages
print_error()        # Error messages
print_info()         # Info messages
print_header()       # Header messages
print_step()         # Step messages
```

### 2. **Configuration Selection Logic**
```bash
case "$config_type" in
    "Basic Training")
        MODEL_NAME="HuggingFaceTB/SmolLM3-3B"
        DATASET_NAME="HuggingFaceTB/smoltalk"
        # ... other parameters
        ;;
    "A100 Large Scale")
        MODEL_NAME="HuggingFaceTB/SmolLM3-3B"
