+# Phase 27 Plan 03: Root Layout Integration Summary
+
+**TopNav replaces TotalsBar across all pages, BottomTabBar wired for mobile, hero removed from landing page, and /setups added as a public route**
+
+## Performance
+
+- **Duration:** ~3 min
+- **Started:** 2026-04-10T21:46:00Z
+- **Completed:** 2026-04-10T21:47:55Z
+- **Tasks:** 2 auto + 1 checkpoint (auto-approved)
+- **Files modified:** 2
+
+## Accomplishments
+
+- Swapped TotalsBar for TopNav in root layout — persistent top nav now appears on every page
+- BottomTabBar added to root layout — renders itself only on mobile via md:hidden in the component
+- FAB wrapped in hidden md:block — invisible on mobile, unchanged on desktop
+- /setups added to isPublicRoute — anonymous users can navigate directly to the setups index
+- Root div gains pb-16 md:pb-0 — content not cut off by fixed bottom tab bar on mobile
+- Hero section removed from landing page — starts directly with Popular Setups, search moved exclusively to TopNav
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Wire TopNav, BottomTabBar, and FAB changes into __root.tsx** - `d99ebbd` (feat)
+2. **Task 2: Remove hero section from landing page** - `c628d6b` (feat)
+3. **Task 3: Verify full navigation flow** - auto-approved checkpoint (no commit)
+
+## Files Created/Modified
+
+- `src/client/routes/__root.tsx` - Replaces TotalsBar with TopNav, adds BottomTabBar, hides FAB on mobile, extends public routes, adds mobile bottom padding
+- `src/client/routes/index.tsx` - Removes HeroSection function and all unused imports (Link, Search, useAuth, useUIStore); LandingPage now renders content sections only
+
+## Decisions Made
+
+None — integration plan executed exactly as specified. All components and patterns were established in Plans 01 and 02.
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Issues Encountered
+
+None. The automated verification grep used double-quotes to match `/setups"` but the source file uses single quotes. Manual inspection confirmed the `/setups` public route was correctly inserted.
+
+## User Setup Required
+
+None — no external service configuration required.
+
+## Next Phase Readiness
+
+- Complete navigation restructure for Phase 27 is done (all 3 plans)
+- All 17 locked decisions (D-01 through D-17) satisfied
+- TopNav with search, BottomTabBar for mobile, Setups as top-level route, Collection with 2 tabs, landing without hero — all wired
+- Phase 27 is ready for verifier/transition
