 `advanced_settings` — one function, the full interactive configuration path.
 
+Application scripts may optionally define `advanced_settings_app_configure` and
+`advanced_settings_app_summary`. The first runs before the confirmation dialog

+dialog. This keeps application-specific settings in the script without
+replacing or parsing the shared wizard. Both callbacks are optional and are
+never called by default or silent installs.
