getAdapter() returned the runtime player or GSAP timeline adapter directly when its duration was > 0, even when the document's timeline (computed from sub-composition data-start + data-hf-authored-duration attributes) extended beyond that duration. This capped the seek slider, seek clamping, and sub-composition visibility at the adapter's shorter value. Now each adapter path checks whether the document duration exceeds the adapter's own duration. When it does, the adapter falls through to createStaticSeekPlaybackAdapter which wraps the runtime player with the correct effective duration, allowing seeking and preview across the full timeline range.
