<objective>
Build the full-screen, catalog-driven onboarding flow UI with five steps: Welcome, Hobby Picker, Item Browser, Review, and Done. Includes hobby card selection, popular item grid with check/uncheck, review list with remove, and smooth CSS transitions between steps. All components follow the UI-SPEC design contract exactly.

### Task 1: Create onboarding hooks for data fetching and mutations

<read_first>
- src/client/hooks/useGlobalItems.ts
- src/client/hooks/useSettings.ts
- src/client/lib/api.ts
</read_first>
<action>
Create `src/client/hooks/useOnboarding.ts`:

```ts
import { useMutation, useQuery, useQueryClient } from "@tanstack/react-query";
import { apiGet, apiPost } from "../lib/api";

interface PopularItem {
  id: number;
  brand: string | null;
  model: string;
  category: string | null;
  weightGrams: number | null;
  priceCents: number | null;
  imageFilename: string | null;
  imageUrl: string | null;
  description: string | null;
  ownerCount: number;
}

/** Fetch popular catalog items for the given tags */
export function usePopularItems(tags: string[]) {
  return useQuery({
    queryKey: ["popular-items", tags],
    queryFn: () =>
      apiGet<{ items: PopularItem[] }>(
        `/api/discovery/popular-items?tags=${tags.join(",")}&limit=24`,
      ).then((res) => res.items),
    enabled: tags.length > 0,
  });
}

/** Complete onboarding by batch-adding selected items */
export function useCompleteOnboarding() {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: (globalItemIds: number[]) =>
      apiPost<{ itemsCreated: number; categoriesCreated: string[] }>(
        "/api/onboarding/complete",

      ),
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ["settings"] });
      queryClient.invalidateQueries({ queryKey: ["items"] });

<automated>grep "usePopularItems" src/client/hooks/useOnboarding.ts && grep "useCompleteOnboarding" src/client/hooks/useOnboarding.ts && echo "PASS" || echo "FAIL"</automated>
</verify>
<acceptance_criteria>
- `usePopularItems` hook accepts `tags: string[]` and fetches from `/api/discovery/popular-items`
- Query is disabled when tags array is empty (`enabled: tags.length > 0`)
- `useCompleteOnboarding` mutation POSTs to `/api/onboarding/complete`
- On success, invalidates `settings`, `items`, and `categories` query keys
- Both hooks use `apiGet`/`apiPost` from `lib/api`

- `OnboardingFlow` manages 5 steps: welcome, hobby, browse, review, done
- Full-screen overlay: `fixed inset-0 z-50 bg-white overflow-y-auto`
- Step transitions: opacity-0/-translate-y-4 to opacity-100/translate-y-0 with 200ms exit + 300ms enter
- StepIndicator shows progress: welcome=20%, hobby=40%, browse=60%, review=80%, done=100%
- Hobby selection resets item selections when changed
- Review step gets items from popularItems filtered by selectedItemIds
- Confirm calls `useCompleteOnboarding` mutation, then transitions to done step
- Skip calls `useUpdateSetting` to set onboardingComplete and triggers onComplete
- `onComplete` prop called on final "Start exploring" click and all skip paths

| Threat | Severity | Mitigation |
|--------|----------|------------|
| XSS via catalog item model/brand names | Low | React auto-escapes JSX text content; no dangerouslySetInnerHTML used |
| Stale popular items cache showing removed items | Low | React Query default staleTime; items fetched fresh on hobby change |
| UI state manipulation via browser devtools | Low | Server-side validation on /api/onboarding/complete; UI state is convenience only |
