+patterns-established:
+  - "Route-aware TotalsBar: optional stats/linkTo/title props with backward-compatible default"

+# Phase 3 Plan 2: Setup Frontend Summary
+
+**Dashboard with summary cards, setup CRUD UI with category-grouped item picker, and route-aware TotalsBar**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-03-15T11:45:33Z
+- **Completed:** 2026-03-15T11:50:33Z
+- **Tasks:** 2
+- **Files modified:** 14
+
+## Accomplishments
+- Dashboard at / with three summary cards linking to Collection, Planning, and Setups
+- Full setup CRUD UI: list page with inline create, detail page with item management
+- ItemPicker component in SlideOutPanel for checklist-based item assignment to setups
+- Route-aware TotalsBar that shows contextual stats per page
+- Navigation restructure moving collection to /collection with GearBox title linking home
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Navigation restructure, TotalsBar refactor, and setup hooks** - `86a7a0d` (feat)
+2. **Task 2: Setup list page, detail page, and item picker** - `6709955` (feat)
+
+## Files Created/Modified
+- `src/client/routes/index.tsx` - Dashboard page with three DashboardCard components
+- `src/client/routes/collection/index.tsx` - Collection page with gear/planning tabs (moved from /)
+- `src/client/routes/setups/index.tsx` - Setup list page with inline create form and SetupCard grid
+- `src/client/routes/setups/$setupId.tsx` - Setup detail with category-grouped items, totals bar, item picker, delete
+- `src/client/routes/__root.tsx` - Route-aware TotalsBar props, FAB visibility, resolve navigation update
+- `src/client/components/TotalsBar.tsx` - Refactored to accept optional stats/linkTo/title props
+- `src/client/components/DashboardCard.tsx` - Dashboard summary card with icon, stats, empty text
+- `src/client/components/SetupCard.tsx` - Setup list card with name, item count, weight, cost
+- `src/client/components/ItemPicker.tsx` - Checklist picker in SlideOutPanel for item selection
+- `src/client/components/ItemCard.tsx` - Added optional onRemove prop for setup item removal
+- `src/client/hooks/useSetups.ts` - TanStack Query hooks for setup CRUD and item sync/remove
+- `src/client/hooks/useItems.ts` - Added setups invalidation on item update/delete
+- `src/client/stores/uiStore.ts` - Added itemPicker and confirmDeleteSetup UI state
+- `src/client/routeTree.gen.ts` - Updated with new collection/setups routes
+
+## Decisions Made
+- TotalsBar refactored with optional props rather than creating separate components per page
+- Setup detail computes totals client-side from items array (avoids extra API call)
+- ItemPicker tracks selections locally, syncs batch on Done (not per-toggle)
+- FAB restricted to /collection gear tab only (hidden on dashboard and setups)
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- All frontend features complete, ready for visual verification in Plan 03
+- All 87 backend tests still passing
+- TypeScript compiles clean (only pre-existing warnings in CategoryPicker/OnboardingWizard)
