- the rail's top button cycles system, light and dark and names the
current choice; light and dark ignore prefers-color-scheme
- usePreferences applies the cached theme before the first await of boot,
saves the choice through PUT /account/preferences and reverts with a
toast when the save fails; me() applies the stored preference
- useSidebar: collapsed below 1100px (matchMedia) or by the admin's choice,
persisted as a boolean under summer-admin.sidebar; the viewport never
overwrites the stored choice
- SectionPanel collapse and rail expand buttons; SectionFlyout (role menu)
opens on hover, focus, Enter or ArrowDown on a rail item, closes on Esc or
about 200 ms after leaving and returns focus to the rail item
- Breadcrumbs with plugin, controller and record crumbs; UserMenu (Reka
DropdownMenu) with initials, name, role and Wyloguj
- useAuth.logout POSTs /auth/logout, clears user, navigation and settings
and routes to login even when the call fails
- applyColorScheme toggles .dark from prefers-color-scheme (no toggle, A6)
- newest toast first, 200 ms fade and scale for dialogs and toasts
- one relation-manager type constant in the registry
- shell smoke tests; tests default to a desktop, light matchMedia
