Proposed Changes
This is the start of an update to adv_app.py to address:

Request: I noticed adv_app.py isn't really idiomatic. Maybe we should create an idiomatic version of it that uses fast_app, modern routing stuff, avoids fastlite .dataclass(), etc?

To get this out of draft: adv_app.py must be completely updated.

@Isaac-Flath I think we misunderstood your bringing in of your monsterification branch. It appears to reset a number of changes we made to make the PR more idiomatic. This is probably my fault, I told you to bring it in without looking at it.

We could build off your branch, renaming and reconstructing things accordingly. As we're out of time we'll pick up on that tomorrow.
