QuartileTracker

public struct QuartileTracker

A value type that tracks quartile progress for a single ad playback.

Reset via reset() whenever a new ad starts, then call evaluate(ad:progress:fire:) on every progress update. The tracker guarantees forward-only state progression: none → first → mid → third.
