No A0 CLI connection or host browser setup is needed. Uses Chrome, Edge, Brave, Opera, Vivaldi, or Chromium on the A0 CLI host. Keep A0 CLI connected; the browser opens when the agent first needs it. For an already-open browser, use its inspect page, such as chrome://inspect/#remote-debugging or opera://inspect/#remote-debugging, and enable "Allow remote debugging for this browser instance". deployed_codeInternal Docker browser selected.
