"""
One-time script: adds "Meta Ads Campaigns" and "MetaCampaignMes" tables to the
EXISTING Airtable base shared with leads-optimizer (AIRTABLE_BASE_ID), next to
"Google Ads Campaigns" / "GACampaignMes".

⚠️ This mutates a shared, already-in-production Airtable base used by
leads-optimizer. Run it deliberately, not as part of routine deploys.
Requires an Airtable Personal Access Token with the `schema.bases:write`
scope over that base (AIRTABLE_TOKEN in .env).

Usage:
    python setup_airtable_meta_tables.py

  Listo. En Airtable ya existen 'Meta Ads Campaigns' y 'MetaCampaignMes'.
  No hace falta añadir nada a .env: AIRTABLE_TOKEN / AIRTABLE_BASE_ID
  ya son los mismos que usa leads-optimizer.
