Removing all instance variables to decouple variable name choices
between actions that re-use templates, and to remove the additional
cognitive load of learning what an instance variable is. Also,
avoiding state is better practice anyway, IMO.
Using strings as keys to the params hash following the heuristic:
"If we could change it to 'zebra' on a whim, then use a string;
otherwise use a symbol."
Making variable and input names longer and more pedantic.
