CNCjs Deploy for NU31 Infra

This repository deploys cncjs, a web interface for CNC controllers running Grbl, Marlin, Smoothieware, TinyG or g2core, to the existing infra Docker Swarm.

Notes

• update_config.order is stop-first, two instances would fight over the .cncrc file and, with a controller attached, over the serial port.
• The app publishes no port of its own, the only way in is caddy.
• The stack uses no environment variables, so the workflow deploys without an env file.
