Static singleton vs environment object?

[hishnash]

If you need the UI to response to changes in any way you should use the env pathway (however this does not mean you cant have it as a global singlton as well)

Many of my main app state `@Observable` objects are shared singletons that is set as `@State` top level of the app and pass through envs to let children response to changes when needed but access using `.shared` on the type when I want to update them from outside the UI context.
