  template: `
    <div>{{ consumerSignal().title }}</div>
    <div>{{ computedRole() }}</div>
  `
})
export class UserProfileComponent {
  consumerSignal = sign<User | null>(null);
  
  computedRole = computed(() => {
    const consumer = this.consumerSignal();
    return consumer ? this.functionService.getRole(consumer.id) : 'visitor';
  });
}
