"""
Third-party application configuration for thrillwiki project.

This module configures third-party Django applications including:
- django-allauth (authentication)
- Celery (task queue)
- Health checks
- Tailwind CSS
- Cloudflare Images
- Road Trip service

Why python-decouple?
- Already used in base.py for consistency
- Simpler API than django-environ
- Sufficient for our configuration needs
- Better separation of config from code
