Sphere Sei Shōnagon puzzle

A ball on a stand: an eight-sided globe, as round as seven straight-edged pieces can make it, resting on a square block. It is rated hard because the globe is a convex shape with no corner that belongs to one piece. About two thirds of the pieces' edges are hidden inside it, nearly as many as in the square.

Drag the seven Sei Shōnagon pieces onto the shadow until the sphere is filled. Every shape here uses all seven, with no overlaps and nothing hanging over the edge. The pieces have exactly the silhouette's area, so covering the shadow is the whole win condition.
