Answered.
The masthead sits above the fold at the very top of the page. On load it can start collapsed and expand to its full 970×250 height, shifting the article content down smoothly instead of covering it. Because the unit is part of the page flow (not an overlay), it is immune to banner blindness at the top slot and measures full viewability for every expanded impression.
On mobile the placement maps to a responsive top billboard (for example 320×100 or 5:1 adaptive banners), or the flight rotates to a mobile anchor. The 970×250 unit itself is desktop.
