## 🎯 What Changed

### ✅ Navigation Simplified
```
BEFORE: [Prep] [Trade] [Review] ... [AI Coach] [ML Patterns] [Settings] [Prompts]
AFTER:  [Dashboard] [Trade] [Journal] [AI Coach] [Settings]
```

### ✅ Settings Promoted
```
BEFORE: Settings buried in "legacy" section at bottom of page
AFTER:  Settings in primary navigation bar (1 click to access)
```

### ✅ Code Organized
```
BEFORE: Complex dual-state navigation, scattered render functions
AFTER:  Single activeView state, 5 focused view components
```

### ✅ Type System Simplified
```
BEFORE: MainTab, LegacyTab, WorkflowTabConfig, StepMeta types
AFTER:  MainView type, NavItem interface, NAV_ITEMS config
```

## 🎓 Key Learnings

### Architecture Improvements
✅ **Single Source of Truth** - One NAV_ITEMS array, not three separate ones
✅ **Type Safety** - 2 focused types instead of 4 scattered ones
✅ **Clean Separation** - Each view is independent, easier to test
✅ **Maintainability** - Clear structure makes future changes easier

### Code Quality
✅ **Zero TypeScript Errors** - In the refactored component
✅ **DRY Principle** - No data duplication
✅ **Clear Naming** - `activeView` is clearer than `activeTab` + `legacyTab`
✅ **Proper Hooks** - Correct React usage with useCallback

### User Experience
✅ **Improved Navigation** - 5 focused views vs 7 scattered tabs
✅ **Better Access** - Settings in primary nav, not buried
✅ **Professional Look** - Sticky navigation, consistent styling
✅ **Mobile Friendly** - Responsive design works well on all screens
