Overhead Pepperoni Pizza Photo

Create a high-quality professional overhead product photograph of a whole pepperoni pizza centered on a clean bright white seamless studio background. The pizza should be perfectly round and fill most of the square frame, photographed from directly above with soft studio lighting and a subtle natural shadow around the crust. Show a thin-to-medium golden-brown crust with darker toasted bubbles around the rim, rich red tomato sauce visible near the edges, glossy melted mozzarella cheese with lightly browned spots, fine dried herb seasoning scattered across the cheese, and exactly 21 round pepperoni slices arranged evenly across the surface in a balanced pattern from edge to center. Make the pepperoni deep red-orange, shiny with rendered oil, slightly curled at the edges, and speckled with seasoning. Keep the composition appetizing, realistic, crisp, and commercial-food-photography quality, with no plate, no text, no hands, no props, and no background clutter.
