- tmux-web-attach.sh: attach browser to one window via link-window into a private temp session (no session-group pollution); window-size smallest while attached so the browser never gets cut off; mouse on for natural wheel/touch scrolling; status bar off; destroy-unattached cleanup - start-ttyd.sh: ttyd on 127.0.0.1:7681, base path /term, url-arg enabled, Tokyo Night theme, system mono stack, fontSize 14 - systemd user unit + install script registration - nginx: /term/ proxied with websocket upgrade, gated by auth_request to the kanban cookie check; unauthenticated -> 302 /login Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
