清晨运动公园：日常使用的层次

Show a community sports park at six in the morning, when its ordinary users have it to themselves. Render low warm sun coming in almost horizontally, throwing very long shadows from every tree and post across the dew-wet grass, with a faint mist lying in the lowest part of the site. Populate it with the real early crowd rather than models: older people doing slow group exercise on a shaded deck, two runners on the track at different paces, a person walking a dog on the loop, a lone shooter on the basketball court, someone doing pull-ups at the fitness rig, and a groundskeeper opening the equipment store. Detail the traces of the hour — dew tracks across the grass where people have walked, a sprinkler still running on the far field, floodlights just switched off, a delivery of line marking paint by the gate. Keep the built elements secondary and the light and activity primary. Show a cool blue in the shadows against warm gold on the lit surfaces. Photorealistic, atmospheric, quiet and alive, low eye-level view across the park.
