+# Phase 07 Plan 01: Setup Wizard UI Shell Summary
+
+LocalStorage-synced 3-step wizard with income input, grouped preset checklist (19 items), live allocation bar, and horizontal stepper navigation.
+
+## Commits
+
+| Task | Commit | Description |
+|------|--------|-------------|
+| 1 | bbcb07f | useWizardState hook, i18n keys (EN+DE), shadcn checkbox |
+| 2 | e141197 | All 7 wizard UI components and SetupPage orchestrator |
+
+## What Was Built
+
+1. **useWizardState hook** - Manages wizard step, income, and item selections in localStorage keyed by userId. Validates JSON shape on load (T-07-01 mitigation). Bills and variable_expense items pre-checked by default.
+
+2. **WizardStepper** - Horizontal 1-2-3 stepper with circles, connector lines, and step labels. Completed steps are clickable; future steps are disabled.
+
+3. **IncomeStep** - Number input pre-filled with 3000, currency suffix from profile, helper text, and inline validation error display.
+
+4. **AllocationBar** - Sticky bar showing remaining = income - sum(checked amounts). Green when positive, red (destructive) when negative. aria-live="polite" for screen readers.
+
+5. **CategoryGroupHeader** - Colored dot + label + item count for each of the 6 category types.
+
+6. **PresetItemRow** - Checkbox + preset name (i18n) + category badge with colored border + editable amount input (disabled when unchecked).
+
+7. **RecurringItemsStep** - Groups all 19 PRESETS into 6 category sections with AllocationBar at top.
+
+8. **SetupPage** - Page orchestrator: centered card layout (max-w-2xl), loads profile for currency, renders stepper + active step, handles Next/Back/Skip navigation with income validation.
+
+## i18n
+
+All wizard copy added under `setup.*` namespace in both `en.json` and `de.json` (35 keys each). German translations use proper umlauts and natural phrasing.
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Known Stubs
+
+| File | Line | Stub | Reason |
+|------|------|------|--------|
+| src/pages/SetupPage.tsx | Step 3 content | "Review step coming in next plan" placeholder | Plan 02 will implement ReviewStep and completion logic |
+| src/pages/SetupPage.tsx | Skip setup button | No-op onClick | Plan 02 will wire skip to mark setup_completed and redirect |
+| src/pages/SetupPage.tsx | Complete button | Disabled, no handler | Plan 02 will implement completion sequence |
+
+These stubs are intentional -- Plan 02 explicitly owns the ReviewStep, completion logic, routing, and redirect.
