a highly detailed circular school sports festival emblem, perfect circular badge composition, semi-3d enamel emblem craft. the outer ring has a moon-white pearl background with two ultra-thin purple border lines. leave blank space at the top and bottom, no text. the bottom of the inner circle is a curved track, spliced with brick-red and teal-green, with three white track lines, curving upward to form a horizon, fading into a warm-gold morning glow on the right. in the center of the track are two side-by-side semi-circular arches, with dark negative space inside. a warm-gold silhouette of a sprinting teenager is leaping out from the left arch, leaning forward 30 degrees, his back leg morphing into a curled book page, his front foot morphing into a burning torch and three speed lines. above the arches is a tower body with dark red brick vertical texture. the middle of the tower has six slender vertical louver lines extending upwards and overflowing the tower top, transforming into six vertical glowing light bands. the upper part of the tower has a square beige frame containing a white circular stopwatch dial, black cross hands pointing to the upper right, dotted scale marks. above the dial is a row of beige fretwork lines. the tower top is flat with a railing, a thin silver-white antenna pointing straight up, morphing into a torch flame. on the right side of the tower is a low-contrast red brick teaching building silhouette and two dark green tree canopies (white trunks), creating a balanced composition. in the sky, three overlapping thin rings (pale purple, teal green, warm gold). the main color palette is brick red, warm gold, teal green, and moon white, with purple only in thin lines (less than 15%). top-left 45-degree main light, soft inner shadows, edge highlights, high-end gradients. full composition, strong dynamic, breathable negative space. bottom center reserved for small text. crisp vector edges, no text, pure white background, no mockup.
