TrackOnView
TrackOnView(
__namedParameters):ReactElement
Emits event exactly once, the first time its host element is
viewport-qualified (plan 144 TASK-13 / REQ-21). Falls back to firing on render
when IntersectionObserver is unavailable (AC-10 degradation). The one-shot
guard is a ref that survives React Strict Mode’s development double-mount, so
the event fires once, not twice (AC-12). Renders its children in the host
element and never throws without a provider (AC-13).
