See how stage and prod differ, service by service.

## New

- ZopDay: open Compare environments on the project page to see your services side by side across environments, with differences highlighted. The Copy to button copies environment variables, the port and health-check settings to another environment, and shows every change before it is saved. Secret values are never shown or copied.
