Rather than `HttpContext`, the [`AuthenticationStateProvider`](https://learn.microsoft.com/en-us/aspnet/core/blazor/security/?view=aspnetcore-8.0#authenticationstateprovider-service) service is used to obtain the user authentication state information for setting targeting context.

Blazor applications like this one typically pull ambient contextual data from scoped services. For example, the `UserAgentContext`, `AuthenticationStateProvider` and `ITargetingContextAccessor` are all scoped services. This pattern *breaks* if the feature management services are added as singleton, which is typical in non-blazor web apps.
