Top-Down Apple Counting Desk Scene

Create a square 1:1 photorealistic top-down tabletop scene on a pale gray wood-grain desk. Arrange exactly {argument name="apple count" default="7"} glossy red apples in two neat rows: exactly 4 apples in the upper row and exactly 3 apples in the lower row, evenly spaced, with realistic stems, yellow-red striping, soft shadows, and no extra apples. Place one blue hardcover book partially visible in the upper-left corner, angled slightly, with the spine facing inward and the Chinese title text {argument name="book spine text" default="算法导论"} printed in white on the spine. Place exactly one black fountain pen horizontally in the exact center of the composition between the two apple rows, with gold trim and the metal nib pointing to the right. Place exactly one transparent cylindrical glass in the lower-right corner, filled halfway with clear water, showing refraction, rim highlights, and a soft shadow. Use clean natural studio lighting, realistic scale, crisp focus, overhead perspective, balanced negative space, and strict object placement. Do not add any other objects, hands, labels, plates, leaves, or decorations.
