Hollow square Sei Shōnagon puzzle

A square frame with a square hole in the middle. It is one of the best known Sei Shōnagon figures, since the seven pieces go all the way round the hole without filling it. It is rated medium because the hole is outline too. The edges around it are in plain sight, so only a little over half of the pieces' edges are hidden, where the solid square hides two thirds.

Drag the seven Sei Shōnagon pieces onto the shadow until the hollow square 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.
