Dark chocolate bar broken open on slate with cocoa

A premium chocolate product poster, 8K ultra HD. In the center, a broken piece of dark chocolate reveals a smooth, velvety interior texture, with a few small crumbs at the edges. Scattered around are cocoa powder, whole cocoa beans, and a few gold foil flakes. The chocolate rests on a dark gray natural slate surface, with a background gradient from deep brown to dark red — understated and luxurious. A soft side light from the upper right illuminates the chocolate’s texture and sheen, creating chiaroscuro contrast. The overall mood is rich, deep, and sophisticated, with a high-end dessert aesthetic. Macro shot, shallow depth of field, focus locked on the chocolate’s broken edge. Magazine-grade commercial photography, balanced color saturation, highlighting the natural and refined quality of the chocolate.
