## Design System - Shimmer Primitives
- Shimmer widgets are in `packages/design_system/lib/src/widgets/shimmer/`
- Available: `UiShimmer`, `UiShimmerBox`, `UiShimmerCircle`, `UiShimmerLine`, `UiShimmerListItem`, `UiShimmerStatsCard`, `UiShimmerSectionHeader`, `UiShimmerList`
- `UiShimmerList.itemBuilder` takes `(int index)` -- single parameter, not `(BuildContext, int)`
- `UiShimmerBox.borderRadius` accepts `BorderRadius?` (nullable), uses `UiConstants.radiusMd` as default
- All shimmer shapes render as solid white containers; the parent `UiShimmer` applies the animated gradient
- Exported via `design_system.dart` barrel

## Staff App Feature Locations
- Shifts: `packages/features/staff/shifts/` -- has ShiftsPage (tabbed: MyShifts/Find/History) + ShiftDetailsPage
- Home: `packages/features/staff/home/` -- WorkerHomePage with sections (TodaysShifts, TomorrowsShifts, Recommended, Benefits, QuickActions)
- Payments: `packages/features/staff/payments/` -- PaymentsPage with gradient header + stats + payment history
- Home cubit: `HomeStatus` enum (initial, loading, loaded, error)
- Shifts bloc: `ShiftsStatus` enum + sub-loading flags (`availableLoading`, `historyLoading`)
- Payments bloc: uses sealed state classes (`PaymentsLoading`, `PaymentsLoaded`, `PaymentsError`)

## UiConstants Spacing Tokens
- Use `UiConstants.space1` through `UiConstants.space24` for spacing
- Radius: `UiConstants.radiusSm`, `radiusMd`, `radiusLg`, `radiusFull`, `radiusBase`, `radiusMdValue` (double)
- `UiConstants.radiusFull` is a `BorderRadius`, `UiConstants.radiusMdValue` is a `double`

## Barrel Files (Staff Features)
- Shifts: `lib/staff_shifts.dart` exports modules only
- Payments: `lib/staff_payements.dart` (note: typo in filename) exports module only
- Home: `lib/staff_home.dart` exports module only
- These barrel files only export modules, not individual widgets -- skeleton widgets don't need to be added

## Client App Feature Locations
- Coverage: `packages/features/client/client_coverage/`
- Home: `packages/features/client/home/` (no loading spinner -- renders default data during load)
- Billing: `packages/features/client/billing/` (billing_page, pending_invoices_page, invoice_ready_page)
- Reports: `packages/features/client/reports/` (reports_page with metrics_grid, plus 6 sub-report pages)
- Reports barrel: `widgets/reports_page/index.dart`
- Hubs: `packages/features/client/hubs/` (client_hubs_page + hub_details_page + edit_hub_page)

## Staff Profile Sections (shimmer done)
- Compliance: certificates, documents, tax_forms -- all have shimmer skeletons
- Finances: staff_bank_account, time_card -- all have shimmer skeletons
- Onboarding: attire, profile_info (personal_info_page only) -- have shimmer skeletons
- Support: faqs, privacy_security (including legal sub-pages) -- have shimmer skeletons
- Pages that intentionally keep CircularProgressIndicator (action/submit spinners):
  - form_i9_page, form_w4_page (submit button spinners)
  - experience_page (save button spinner)
  - preferred_locations_page (save button + overlay spinner)
  - certificate_upload_page, document_upload_page, attire_capture_page (form/upload pages, no initial load)
  - language_selection_page (no loading state, static list)
- LegalDocumentSkeleton is shared between PrivacyPolicyPage and TermsOfServicePage

## Key Patterns Observed
- BenefitsOverviewPage also has CircularProgressIndicator (not shimmer-ified yet)
- ShiftDetailsPage has a dialog-level spinner in the "applying" dialog -- this is intentional, not a page loading state
- Hub details/edit pages use CircularProgressIndicator as action overlays (save/delete) -- keep as-is, not initial load
- Client home page has no loading spinner; it renders with default empty dashboard data
