Hey all, new to Prefect and trying to find analogies with the Web framework world. A few questions: • Web frameworks have the concept of a global "app" object which serves as a container of all routes/controllers etc. Is there an equivalent in Prefect, i.e. an object that encapsulates all flows/tasks? I'm guessing no but just wanted to double check. • Another common web framework feature is "middleware", functions that wrap around a router handler function (or other middleware). The closest I found in Prefect docs is the state change hooks but they seem more limited in that (a) they run only after the flow/task, not before, and (b) they run only for a given state (e.g. failure), not unconditionally (though I guess you can pass the same hook to all four hook params so that's less problematic). • Finally frameworks often provide a way for storing transient (request lifespan) data, e.g.

flask.g

in Flask or

request.state

in Starlette. Prefect exposes a "runtime context", which looks parallel to the web request but afaict it's immutable, or at least not supposed to be writable by user flows/tasks. Is this possible or all data has to be passed explicitly as function parameters? Thanks for any help!
