  "oneLiner": "On any CI or Selenium host this is noVNC — a browser-viewable live view into a container's desktop.",
  "whatItIs": "The official Selenium Docker images publish 7900 for noVNC, so you can watch a test run by opening http://localhost:7900/?autoconnect=1&resize=scale&password=secret. It is an HTTP endpoint that proxies the container's VNC server into a web page. IANA registers 7900 as mevent, Multicast Event, but that assignment carries no implementation you are likely to meet. If 7900 is open on a build agent or a Kubernetes node, look for selenium/standalone-* or selenium/node-* containers.",
