 *
 * - Pass `null` or `undefined` while data is loading; the hook holds the value
 *   at 0 and won't fire the animation until a real target arrives.
 * - When the target changes, the next animation runs from the value currently
 *   on screen to the new one (e.g. a re-fetched stat eases onward from
 *   mid-flight rather than jumping back to the prior target first).
