 *  - Translating HTTP/network failures into SDK error types
 *
 * Both client-credentials and authorization-code flows hit the same endpoint
 * with the same response shape, so they share this code path.

 * spec uses 400 for things like `invalid_grant` even though the SDK normally
 * reserves 400 for validation errors.
 *
 * Honors timeout, AbortSignal, and exponential-backoff retry on transient
 * failures (matching the main HttpClient's behavior). 4xx responses are not
 * retried since they indicate the credentials themselves are bad.
