Two-slot shell topbar (home, left, center, bell, user menu) with SDK API
(setLeft/setSlot/setTitle/hide/show). All 4 primary surfaces migrated:
Settings and Team Admin to Pattern B (flat tabs), Admin to Pattern C
(category tabs + sidebar), Docs to Pattern A (default).
Backend WS events: package.changed (broadcast), auth.changed (targeted),
notification.all_read. User menu re-fetches on package/auth changes.
Bell syncs read state across tabs.
Error handling pass with .sw-inline-error CSS primitive. Empty state
guidance for Admin Workflows/Groups. Announcement global dismiss via
localStorage. Rebrand assets deployed (both b/e icon variants, wordmarks,
full icon library). Docs outline scroll-to-heading fix.
Bug fixes: ICD security assertion tightened, workflow-demo error surfacing,
signoff display names, hello-dashboard + team-admin/groups.js deleted.
