9- When throwing a `HTTPException`, do not add a `detail=` and use a named status code (`status.HTTP_400_BAD_REQUEST`)
10- Do not return a `dict`, instead create a `class RouteNameResponse`
11  - Locate these classes right above the `def route_name():` function which uses them.
12- Use `Model.one` when a record must exist in order for the business logic to succeed.
13- Do not try/except `Model.one` when using a parameter from the request to pull a record. Let this exception bubble up.
14- Use `model_id: Annotated[TypeID, Path()]` to represent a model ID as a URL path parameter
15- Use the typed route helpers in `app/generated/fastapi_typed_routes.py` for all URL generation.
