"""Fase 1 FIX: el nodo `Buscar Contacto Objetivo - MARCA (phone)` referenciaba
`$json['Token/API']` y `$json['Location ID']` asumiendo que el input previo era
`Datos API Cuenta objetivo - MARCA`. Tras la Fase 1, el input proviene del IF
nuevo (que solo trae `contacts` y `total`). Cambiamos las refs a explícitas.

Idempotente.
