Once server init's screen closed, the whole run was printed again under the frame that had just shown it. Now the password and the next steps are, the whole run goes to /var/lib/llmgw/init.log (0600: it holds the password), and it is printed in full only when init fails. Seen in a draft of the install video, where it scrolled the screen away. The spinner and the text field are written here instead of taken from bubbles, whose packages query the terminal's colours as they load. bubbletea does the same deliberately, so the query stays; the dependency goes.
