Docs only. docs/ui-standards.md names the reference design (StartBar's settings window) and the reference implementation (StartAppImage's SettingsWindow), no longer proposes a shared UI repository, and says where StartBar's settings window differs on purpose: no scrim (a click outside reaches the desktop, so you see the Dock change as you adjust it), its own size, and no first run.
