```tsx
// React PDF — Invoice generation
import { Document, Page, Text, View, StyleSheet, renderToBuffer } from '@react-pdf/renderer';

const styles = StyleSheet.create({
  page: { padding: 40, fontSize: 12 },
  header: { fontSize: 24, marginBottom: 20, color: '#8B5CF6' },
  row: { flexDirection: 'row', justifyContent: 'space-between', marginBottom: 8 },
  total: { fontSize: 16, fontWeight: 'bold', borderTopWidth: 1, paddingTop: 8, marginTop: 16 },
});

function InvoicePDF({ invoice }) {
  return (
    <Document>
      <Page size="A4" style={styles.page}>
        <Text style={styles.header}>Invoice #{invoice.number}</Text>
        {invoice.items.map((item, i) => (
          <View key={i} style={styles.row}>
            <Text>{item.description}</Text>
            <Text>${item.amount.toFixed(2)}</Text>
          </View>
        ))}
        <View style={styles.total}>
          <Text>Total: ${invoice.total.toFixed(2)}</Text>
        </View>
      </Page>
    </Document>
  );
}
