## How to Use

### 1. Loading States
```typescript
import { useLoading } from '@/contexts/loading-context'

const { startLoading, stopLoading } = useLoading()
startLoading('Loading builds...')
// ... async operation
stopLoading()
```

### 2. Skeleton Loaders
```typescript
import { SkeletonBuildCard, SkeletonGrid } from '@/components/ui/skeleton'

if (isLoading) {
  return <SkeletonGrid count={6} type="build" />
}
```

### 3. Toast Notifications
```typescript
import { toast } from '@/lib/toast'

toast.success('Build saved!')
toast.error('Failed', 'Try again')
toast.buildSaved('My Gaming PC')
```

### 4. Async Operations
```typescript
import { useAsync } from '@/hooks/use-async'

const { execute, isLoading } = useAsync(saveBuild, {
  loadingMessage: 'Saving...',
  successMessage: 'Saved!',
  showSuccessToast: true
})

<Button onClick={() => execute(data)} disabled={isLoading}>
  Save
</Button>
```

### 5. Optimistic Updates
```typescript
import { useOptimistic } from '@/hooks/use-async'

const { data: isLiked, updateOptimistically, confirmUpdate } = useOptimistic(false)

const handleLike = async () => {
  updateOptimistically(true) // Instant UI update
  const result = await likeBuild()
  confirmUpdate(result.liked) // Confirm with server
}
```
