校园操场：PU跑道与中央草地的日常

Show the sports ground of an ordinary Taiwanese school, at the scale a school actually gets. Render a running track of only six lanes in cushioned polyurethane, its brick-red surface faded unevenly by sun and patched darker in two places, with white lane lines slightly worn at the bends. Fill the centre with a field of coarse warm-season grass, thin and sandy near the goalmouths, marked out for football with white paint that has half weathered away. Detail the surroundings as a school would have them: a chain-link fence with a hedge behind, a covered walkway linking classroom blocks along one side, a row of old trees giving shade at one end, and a basketball court squeezed into the corner. Include a set of goalposts, a long-jump pit with a battered timber edge, and a stack of hurdles under the walkway. Show scattered students in PE uniform — some running, some sitting on the kerb. Light with hazy midday sun. Photorealistic, ordinary, faded red and dry green, eye-level view.
