Resiliency

The solution uses Microsoft.Extensions.Http with Microsoft.Extensions.Http.Resilience for typed HTTP clients: retries, timeouts, and circuit breaker–style policies suitable for mobile-to-API calls.

• Configure client names and policies in DI registration (see Application / Infrastructure registration in the repo).
• Combine with observability spans for outgoing HTTP (OpenTelemetry instrumentation where enabled).
