城市天际线日转夜延时（建筑节奏）

Cinematic urban time-lapse style, rich color contrast between warm day and cool night. Subject: a bustling modern city skyline with glass skyscrapers, a winding elevated highway in the foreground. Action: a time-lapse of the city as day transitions to night — the sun sets casting long golden shadows across rooftops, then the city lights begin to twinkle on window by window, streams of car headlights forming red and white light trails along the highway. Camera: locked-off static wide shot, no movement. Lighting: from harsh midday daylight, through warm golden hour, into deep blue twilight, then sodium-orange streetlamp blanket. Environment: a metropolis viewed from a distant elevated rooftop, scattered clouds streaking across the sky. Audio: a sweeping cinematic orchestral score rising slowly, layered with distant city ambient hum, faint sirens passing far below, a soft wind across the rooftop.
