## Summary

Deliver `@suaveplan/react-auth` on genesis from scratch at enterprise quality. The core React authentication layer: `AuthProvider`, `useAuth`, `useUser`, `useIsAuthenticated`, token management, session persistence, and integration with `@suaveplan/oauth-client` for Authorization Code + PKCE flows. Ships structured errors via `@suaveplan/error`, OTel span events for sign-in/sign-out/refresh, Storybook stories, and Playwright E2E for the full auth lifecycle.

2. **Token refresh** via `@suaveplan/oauth-client` with automatic retry on 401.
3. **OTel spans** — `auth.sign_in`, `auth.sign_out`, `auth.token_refresh`.
4. **Session persistence** — optional `sessionStorage` / `localStorage` adapter.
5. **Stories** — authenticated state, unauthenticated, loading, `AuthGuard` redirect.
6. **Playwright E2E** — sign-in flow, token refresh, protected route redirect.
