Add an application Internal access section that loads the running
container hostname (skipped for Compose apps), densify configuration
diff and popup-small defaults, dock the server-timing HUD into the
mobile top bar, restyle the 2FA challenge with the auth shell, and
enforce 16px mobile form fonts to prevent iOS zoom.
Move proxy, sentinel, resources, and terminal into the server sidebar
with nested routes and icons; extract navbar status into a shared
status-summary component; add full-width service links and compact
loading support.
