- procurement store refreshes right after a warehouse receipt (arrivals) and
after role/project changes (organization/admin), so the ledger reflects
warehouse actions immediately
- refetchOnWindowFocus enabled on the shared query client
- BroadcastChannel (lib/crossTab.ts): mutations broadcast 'quotes' /
'inventory'; all warehouse pages + the store hook resync open tabs
automatically (receipt in one tab updates the ledger in another)
- warehouse mutations (stock changes) notify other tabs; same-page refresh
behavior unchanged
