Assiette Kaiseki Wagyu et Sashimi

High-end Japanese kaiseki food photography on a [glossy black lacquer plate] against a [deep black] background, captured with [dramatic low-key luxury restaurant lighting], shallow depth of field, and macro lens realism. Diagonal, elegant composition: on the right foreground are exactly three thick slices of medium-rare wagyu beef steak with seared brown crust, pink marbled center, glossy sauce pooling underneath, and delicate flecks of edible gold leaf. In the left midground are exactly four translucent white sashimi slices of [white fish], folded and overlapping with glistening wet highlights, tiny purple edible flowers, and scattered gold leaf. Garnishes include one large red-orange maple leaf in the front left foreground, a sweeping curved dry-brushed gold powder arc along the plate's edge, an upright purple herb flower sprig between fish and beef, two small green wasabi mounds in the back, two pale green rolled garnish rings behind the beef, and a small autumn branch with red maple leaves in the background. Ultra-refined culinary presentation, crisp textures, soft background bokeh, no utensils, no hands, no text.
