When building an Elm front‑end that calls a protected API, I want to use HTTP Basic authentication to convey only the minimal credentials required for each request, following a least‑privilege approach. However, Basic credentials can expire, and the API expects clients to obtain fresh tokens via an OAuth 2.0 refresh‑token flow before retrying the request. I
