 ## Patterns
 
 - Components: PascalCase, one per file, default export
-- API calls: use `services/api.ts` wrappers (`riskApi`, `alertApi`, `caseApi`, `gridApi`) — they handle caching and request dedup
+- Map components: imperative `@geoscene/core` via `createMapView` — do not pass MapView instances between components
-- State: Zustand stores in `stores/`, typed with TypeScript interfaces from `types/`
+- Coordinates: GeoScene uses `[longitude, latitude]`
-- Styling: Tailwind utility classes, no CSS modules

 ## Component Types
 
-**Map components** (`*Map.tsx`) — Leaflet-based maps:
+**Map components** (`*Map.tsx`, `DistrictChoropleth`) — `@geoscene/core`:
-- Use `react-leaflet` / direct Leaflet manipulation via `useRef`
+- Use `createMapView` / layer factories from `@/geoscene`
-- Risk coloring: centralized `RISK_COLORS` and `RISK_LABELS` constants
+- Coordinate system: `[longitude, latitude]` (GeoScene convention)
-- Coordinate system: `[lat, lng]` (Leaflet convention, NOT `[lng, lat]`)
+- Destroy MapView on unmount
 
 **Chart components** (`*Chart*.tsx`) — Recharts:
 - Responsive containers with `width="100%" height={...}`
 
 **Navigation** (`TopNav.tsx`, `SideNav.tsx`):
 - No data fetching — pure navigation/presentation
+- No role/perspective switcher
 
 **Overlay/Utility** (`GridStatsOverlay`, `ErrorBanner`, `StatCard`, `TimelinePlayer`):
 - Small, focused, reusable across pages
 
 ## Data Flow
 
-- Components receive data via props, never fetch directly
+- Components receive data via props, never fetch directly (maps may call tile/cell APIs they own)
 - Callbacks passed as props: `onGridSelect`, `onClosePanel`, `onForecastChange`
-- Complex stateful behavior extracted to custom hooks (e.g., `useTimelineStore`)
 
 ## Anti-Patterns
 
-- Don't fetch data in components — receive via props or store hooks
+- Don't fetch page-level data in leaf components — receive via props or store hooks
 - Don't create god components (>200 lines) — extract sub-components
 - Don't use `any` in prop types — use `unknown` and narrow
-- Don't pass Leaflet map instances between components — each map manages its own instance
+- Don't pass MapView instances between components
-- Don't use CSS modules or inline styles — Tailwind only
+- Don't use CSS modules or inline styles — Tailwind only (map symbol colors excepted)
