+## HTTP client usage in the frontend
+
+- Prefer calling `window.http.wrappedFetch(url, options)` instead of `fetch` directly.
+- The wrapper automatically adds:
+  - `Authorization: Bearer <token>` when available
+  - `X-Correlation-ID` on every request
+  - `Content-Type: application/json` when you pass a string body (e.g., from `JSON.stringify`)
+- It also exposes helpers: `window.http.parseErrorEnvelope`, `window.http.toError`, `window.http.formatAlert`.
+- The global `fetch` remains wrapped for compatibility, but will log a one-time deprecation warning. New code should use `window.http.wrappedFetch`.
