Completes the useCatalog decomposition. After the previous commit
extracted the pure helpers, this one splits the singleton-via-useBetween
store into three slice-specific entry points and migrates a handful of
consumers as proof.
`src/hooks/catalog/useCatalog.ts`
- Internal `useCatalogState` → renamed to `useCatalogStore` and is no
longer exported. The full return shape is unchanged so callers that
still go through the shim see the exact same object.
- Three new exports built on top of the same `useBetween` instance:
- `useCatalogData()` — server-driven read-only slice (rootNode,
offersToNodes, currentPage, currentOffer, frontPageItems,
searchResult, roomPreviewer, isBusy, catalog localization
version, Builders Club counters + timers).
- `useCatalogUiState()` — UI ephemeral state + writers
(isVisible, pageId, previousPageId, currentType, activeNodes,
navigationHidden, purchaseOptions, catalogPlaceMultipleObjects,
plus every `set*` writer including the ones that mutate the
data slice on user-driven selection).
- `useCatalogActions()` — imperative operations only
(openCatalogByType, toggleCatalogByType, activateNode,
openPageBy{Id,Name,OfferId}, requestOfferToMover,
selectCatalogOffer, getNodeBy{Id,Name},
getBuilderFurniPlaceableStatus).
- `useCatalog` is kept as a deprecated shim that returns the full
historical surface, so the 48 existing consumers compile and run
unchanged.
Pilot consumer migrations (3 of 48):
- `CatalogBuildersClubStatusView` — Data (furni counters, seconds
timers) + UiState (currentType).
- `CatalogBreadcrumbView` — UiState (activeNodes) + Actions
(activateNode).
- `CatalogNavigationItemView` — UiState (currentType) + Actions
(activateNode).
Tests: `tests/useCatalog.filters.test.tsx` (5 cases).
`useBetween` is mocked via `vi.hoisted` so the four hooks share one
deterministic fake store — rendering the real `useCatalogStore`
would mount ~30 useState calls + open a fresh RoomPreviewer +
subscribe to a dozen renderer events, which is more than these
contract tests need.
- `useCatalogData` exposes exactly its read-only keys.
- `useCatalogUiState` exposes exactly its UI keys + setters.
- `useCatalogActions` exposes exactly its imperative ops (and
explicitly NOT data fields — proves no leak across slices).
- Singleton identity: callbacks read through the shim are `===` to
the ones read through the slices.
- Shim surface: the historical key set is still present so
un-migrated consumers don't silently break.
Suite: 163/163 (was 158/158). `yarn typecheck` green.

Fix only the cases that are unambiguous anti-patterns; leave the
event-driven setState patterns (useNitroEvent / useMessageEvent
subscriptions, async fetches with cleanup) alone since they're
legitimate in this architecture.
- src/components/catalog/views/catalog-header/CatalogHeaderView.tsx:
displayImageUrl was pure-derived from imageUrl. Drop the useState +
useEffect entirely; compute in render.
- src/components/navigator/views/NavigatorRoomCreatorView.tsx:
the maxVisitors list (10..100 step 10) and roomModels/selectedModel
came from static config; convert to module-level MAX_VISITORS_LIST
constant + useState lazy initializers. Removes 2 init effects.
setCategory(categories[0].id) is left as-is because categories
arrives async from a hook.
- src/components/login/LoginView.tsx:
Replace useEffect(() => setLocalError(null), [step]) with the
React-recommended "track previous prop" render-time reset:
if(prevStep !== step) { setPrevStep(step); setLocalError(null); }
Same observable behavior, no extra render.
- src/components/room/widgets/choosers/ChooserWidgetView.tsx:
Wrap the selectItem callback prop call in useEffectEvent so a
parent re-render that changes selectItem identity doesn't
re-fire the visualizer side-effects.
Net: 4 fewer set-state-in-effect violations; behavior preserved.
The remaining ~328 violations across the codebase are predominantly
legitimate event-bus / async-fetch patterns and need per-case
review with running app, not a sweep.
