# Integration Summary

## ✅ Completed: Apps/Web Integration with Abacus-React Enhancements

### Features Implemented & Integrated

#### 1. **Theme Presets (ABACUS_THEMES)**
**Status:** ✅ Fully integrated

**Files Updated:**
- `apps/web/src/components/MyAbacus.tsx` - Now uses `ABACUS_THEMES.light` and `ABACUS_THEMES.trophy`
- `apps/web/src/components/HeroAbacus.tsx` - Now uses `ABACUS_THEMES.light`
- `apps/web/src/components/LevelSliderDisplay.tsx` - Now uses `ABACUS_THEMES.dark`

**Code Eliminated:** ~60 lines of duplicate theme style definitions

---

#### 2. **Compact Prop**
**Status:** ✅ Fully integrated

**Files Updated:**
- `apps/web/src/app/arcade/complement-race/components/AbacusTarget.tsx` - Now uses `compact={true}`

**Before:**
```tsx
<AbacusReact
  value={number}
  columns={1}
  interactive={false}
  showNumbers={false}
  hideInactiveBeads={true}
  scaleFactor={0.72}
  customStyles={{ columnPosts: { opacity: 0 } }}
/>
```

**After:**
```tsx
<AbacusReact
  value={number}
  columns={1}
  compact={true}
  interactive={false}
  showNumbers={false}
  hideInactiveBeads={true}
  scaleFactor={0.72}
/>
```

---

#### 3. **Utility Functions**
**Status:** ✅ Fully integrated

**Files Updated:**
- `apps/web/src/utils/beadDiff.ts` - Now re-exports from abacus-react
- `apps/web/src/utils/abacusInstructionGenerator.ts` - Now re-exports from abacus-react
- `apps/web/src/components/tutorial/TutorialPlayer.tsx` - Imports `calculateBeadDiffFromValues` from abacus-react
- `apps/web/src/components/tutorial/TutorialEditor.tsx` - Imports `calculateBeadDiffFromValues` from abacus-react

**Exports from abacus-react:**
- `numberToAbacusState()`
- `abacusStateToNumber()`
- `calculateBeadChanges()`
- `calculateBeadDiff()`
- `calculateBeadDiffFromValues()`
- `validateAbacusValue()`
- `areStatesEqual()`

**Code Eliminated:** ~200+ lines of duplicate utility implementations

---

#### 4. **React Hooks**
**Status:** ✅ Exported and ready to use

**Available Hooks:**
- `useAbacusDiff(fromValue, toValue, maxPlaces)` - Memoized bead diff calculation
- `useAbacusState(value, maxPlaces)` - Memoized state conversion

**Not yet used in app** (available for future tutorials)

---

#### 5. **Column Highlighting**
**Status:** ✅ Implemented, not yet used

**New Props:**
- `highlightColumns?: number[]` - Highlight specific columns
- `columnLabels?: string[]` - Add educational labels above columns

**Usage Example:**
```tsx
<AbacusReact
  value={123}
  highlightColumns={[1]}
  columnLabels={['ones', 'tens', 'hundreds']}
/>
```

---

### Code Deduplication Summary

**Total Lines Eliminated:** ~260-300 lines

**Breakdown:**
- Theme style definitions: ~60 lines
- Utility function implementations: ~200 lines
- Custom styles for inline abacus: ~5-10 lines per usage

---

### Remaining Work (Optional Future Enhancements)

1. Use `highlightColumns` and `columnLabels` in tutorial components
2. Replace manual bead diff calculations with `useAbacusDiff` hook in interactive tutorials
3. Use `useAbacusState` for state inspection in debugging/development tools
4. Consider implementing `frameVisible` toggles in settings pages

---
