## Architecture

Three separate front ends share one API and one database, which is what keeps
merchant, rider and admin workflows from leaking into each other while still
reporting on the same shipment.

Shipment flow: booking through to rider delivery

- Merchant app → NestJS API
- Admin app → NestJS API
- Rider PWA → NestJS API
- NestJS API → PostgreSQL
- NestJS API → BullMQ / Redis
- NestJS API → Cloudflare R2

The queue carries the work that must not block a booking: SMS dispatch, label
generation and bulk imports.
