How this differs from a name wheel
A name list is open-ended. A number wheel is a closed range: you choose the bounds, generate every integer in that span (up to 400 slices), and spin. Changing min/max and pressing “Load numbers” rebuilds the wheel — it does not keep leftover names mixed in.
Fairness
Each integer in the loaded range has the same chance. The winning number is selected with cryptographic randomness before the animation runs.
