A top-down overhead photograph looking straight down at a round frosted cake on a white marble surface. The cake is pre-cut into six large jigsaw-puzzle-piece slices with matching tab-and-socket edges. Every cut line between adjacent pieces shows a raised tab on one piece meeting a matching socket on its neighbour, the way real jigsaw puzzle pieces interlock. The frosting is smooth white buttercream, crushed pistachios are pressed into the sides, and one slice is being lifted slightly above the cake on a cake server, revealing the sponge and raspberry filling layers. The remaining five slices stay in place with their jigsaw edges visibly matching their neighbours. A small plate with two gold forks and a linen cloth sit beside the cake stand on the marble. Soft natural window light from the upper left, gentle shadows within the cut lines. No text appears anywhere. 1:1 square composition.
