  --background: 0 0% 100%;
  --foreground: 222.2 84% 4.9%;
  --primary: 221.2 83.2% 53.3%;
  --primary-foreground: 210 40% 98%;
  /* Add your custom colors */
}
```

### Adding New Languages

{
  "common": {
    "welcome": "Your translation",
    "loading": "Your translation"
  }
}

// lib/i18n.ts - Register new language
import yourLanguage from './locales/your-language.json';

resources: {
  'your-lang': { translation: yourLanguage }
}
```

### Custom Components

```tsx
// components/ui/your-component.tsx
import { cn } from '~/lib/utils';
import { Text } from '~/components/ui/text';

interface YourComponentProps {
  className?: string;
  children: React.ReactNode;
}

export function YourComponent({ className, children }: YourComponentProps) {
  return (
    <Text className={cn('your-default-styles', className)}>
      {children}
    </Text>
  );
}
```

## 📱 Usage Examples

### Basic Form with Validation

```tsx
import { useForm } from 'react-hook-form';
import { zodResolver } from '@hookform/resolvers/zod';
import { z } from 'zod';
import { Button } from '~/components/ui/button';
import { Input } from '~/components/ui/input';

const schema = z.object({
  email: z.string().email(),
  password: z.string().min(8),
});

export function LoginForm() {
  const { register, handleSubmit, formState: { errors } } = useForm({
    resolver: zodResolver(schema)
  });

  return (
    <View className="space-y-4">
      <Input
        placeholder="Email"
        {...register('email')}
        error={errors.email?.message}
      />
      <Input
        placeholder="Password"
        secureTextEntry
        {...register('password')}
        error={errors.password?.message}
      />
      <Button onPress={handleSubmit(onSubmit)}>
        Login
      </Button>
    </View>
  );
}
```

### Data Table with Filtering

```tsx
import { Table } from '~/components/ui/table';
import { useTable } from '~/lib/hooks/useTable';

const columns = [
  { accessorKey: 'name', header: 'Name' },
  { accessorKey: 'email', header: 'Email' },
  { accessorKey: 'role', header: 'Role' },
];

export function UsersTable() {
  const [globalFilter, setGlobalFilter] = useState('');
  
  return (
    <Table
      data={users}
      columns={columns}
      enableSorting
      enableFiltering
      globalFilter={globalFilter}
      onGlobalFilterChange={setGlobalFilter}
      enablePagination
      pageSize={10}
    />
  );
}
```

### Bottom Sheet Implementation

```tsx
import { BottomSheetModal, BottomSheetView } from '~/components/ui/bottom-sheet';

export function ProfileModal() {
  const [isOpen, setIsOpen] = useState(false);

  return (
    <BottomSheetModal
      open={isOpen}
      onOpenChange={setIsOpen}
      snapPoints={['50%', '90%']}
    >
      <BottomSheetView className="p-6">
        <Text className="text-2xl font-bold mb-4">User Profile</Text>
        {/* Your content here */}
      </BottomSheetView>
