Blog App (Coop)

Blog, authentication, and content management service for the Rose Ash cooperative platform. This is the primary "coop" app — it handles Ghost CMS integration, user auth, and admin settings.

Architecture

One of four Quart microservices sharing a single PostgreSQL database:

App	Port	Domain
blog (coop)	8000	Auth, blog, admin, menus, snippets
market	8001	Product browsing, Suma scraping
cart	8002	Shopping cart, checkout, orders
events	8003	Calendars, bookings, tickets

Cross-App Integration

• Login adoption: When a user logs in via magic link, auth/routes.py emits a user.logged_in domain event. The glue layer's login_handlers.py picks it up and adopts anonymous cart items + calendar entries.
• Cart widget: Context processor fetches cart summary via internal_api.get("cart", "/internal/cart/summary").
• Internal API: /internal/coop/ endpoints serve blog data to other apps.
