Support a custom accent theme across nav, terminal, scrollbars, and loaders.
Improve light-mode tokens, helper popup placement, and theme persistence
(including purple→custom migration). Cover with appearance and scrollbar tests.
Group service domain tables with inline redirect controls, live-save
redirects without full refreshes, and only auto-pair www hosts when a
www redirect is active. Align helper tooltips, server-timing HUD, and
loading spinners with dark-theme accents; default theme-color to dark.
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.
