Three Rice Balls on a Picnic Cloth

Generate exactly one original image, a single finished food photograph with aspect ratio 3:2. Three hand-formed triangular rice balls sit in an open shallow wooden lunch box on a muted blue gingham picnic cloth. One rice ball is cut to reveal a vivid salmon and shiso center, while two stay whole with narrow strips of dark nori. Soft tree-filtered afternoon sunlight, a small pickled plum in the corner, natural rice grains and imperfect hand-shaped edges, diagonal overhead view, relaxed outdoor lunch story with no hands.
