┌─────────────────────────────────────────────────┐
│ ✅ Successfully integrated Data Analyzer output │
│ 12 variables • 8 constraints                    │
└─────────────────────────────────────────────────┘

When false:
┌─────────────────────────────────────────────────┐
│ ⚠️ Using domain templates (no data from DA)     │
└─────────────────────────────────────────────────┘
```

### Model Metrics (4 Cards)
```
┌─────────────┬─────────────┬─────────────┬─────────────┐
│  Variables  │ Constraints │Architecture │   Quality   │
│     12      │      8      │ Hybrid LLM  │     95%     │
│ From Data   │ From Data   │ FMCO-based  │ Validation  │
└─────────────┴─────────────┴─────────────┴─────────────┘
```

### Problem Configuration

```

### Variables Preview (6 shown)
```
┌──────────────────────────────────┐
│ FactoryA_Product1                │
│ Production quantity for Product1 │
│ continuous | 0 to 1000           │
└──────────────────────────────────┘
```

### Constraints Preview (4 shown)
```
┌──────────────────────────────────┐
