"""
One-time script: adds the 'daily_metrics' table to the EXISTING
meta_optimizer_formacion database in Baserow (created by setup_baserow.py).

Un registro por día con los totales agregados de todo el bloque Formación
(spend, leads_meta, leads_at, ing_meta, ing_at, margin, margin_pct). Se
persiste cada día al ejecutar run.py para no depender de poder volver a
pedirle a Meta el histórico diario más adelante (la API no garantiza
retención ilimitada), y para que el dashboard pueda leerlo sin llamar a
Meta/Airtable cada vez.

Usage:
    python add_daily_metrics_table.py
