Meta access token needed

This reads the Meta Marketing API directly. The token lives in the META_ACCESS_TOKEN environment variable and is never sent to the browser, so it cannot be pasted in here.

Meta tokens expire. A user token lasts ~60 days. For one that does not expire, generate it under Business Settings → Users → System Users with the ads_read permission.
