Axios: browserApiClient from @/lib/api/client for all backend calls.
TanStack Query: wrap every fetch/mutation in a hook under hooks/ (see useHealthQuery).
Zustand: UI state (modals, filters, toggles) goes in stores under stores/.
TanStack Query Devtools: floating panel to inspect query cache, refetch, and debug mutations. Already wired in AppProviders, toggle with Ctrl+Shift+D in dev.
CI: runs on every push and pull request — including your forks. Check the Actions tab for lint, format, typecheck, test, and build results.
