What a spinner is
A spinner is the second die kind. It behaves as a randomizer, but its value comes from wheel slices and arm rotation instead of polyhedral faces.
How the system uses spinners
- the system stores spinners with a die kind of
spinner - spinner slices define weighted outcomes and labels
- the arm position resolves the selected result
- spinner-specific rendering and editing stay in the die family rather than becoming a separate top-level entity type
