- Screen readers get the formatted number as plain text; the rolling strips are aria-hidden.
- `live` opts in to polite announcements of changes; leave it off for numbers that change often.
- Defaults to en-US formatting so server and client match.
- prefers-reduced-motion: reduce (or data-rad-fx-motion="reduce" on an ancestor) swaps digits without rolling.
