ConfigFieldControl

The control a field asks to be drawn with, where the ordinary one for its type reads badly. Opt-in per field rather than inferred, because a slider is right for a value you feel for and wrong for one you have to hit exactly, and tags is right for a comma-separated line that is really a SET and wrong for one that is prose. Nothing about the stored value changes either way

type ConfigFieldControl = 'slider' | 'tags';
