"""
Configuration settings for eamco_scraper.

This module provides configuration with environment-based switching:
- LOCAL: Uses 'eamco' database, localhost CORS origins
- PRODUCTION: Uses 'auburnoil' database, production domain CORS origins

Environment variables are loaded from .env.local or .env.prod depending
on the Docker compose file used.
