 - **Containerized**: Fully Dockerized for easy setup using `docker-compose`.
 
 ## Architecture
-- **Backend**: Go (Gin framework), SQLite for watch history, optimized for `linux/amd64`.
-- **Frontend**: Next.js utilizing React Server Components and standalone output for minimal container footprint.
+- **Backend & Frontend**: Go (Gin framework) and Next.js are combined into a single unified Docker container using a multi-stage `Dockerfile`. 
+- **Process Management**: `supervisord` manages the concurrent execution of the backend API and Next.js frontend within the same network namespace.
+- **Data storage**: SQLite is used for watch history, optimized for `linux/amd64`.
