רביעיית כלי קשת על הגג בשעה הכחולה

A single continuous 5-second vertical shot on a rain-slick rooftop at blue hour. Four young string players perform around a glowing amber table while the skyline flickers behind them. Start close on a violinist bowing, then pull backward and rise to reveal the full quartet, their hands, instruments, sheet music, and puddle reflections. Warm practical lamps, soft rain, expressive but natural movement, cinematic 35mm lens, realistic live-performance sound: strings, light rain, distant traffic. No text, logos, or captions.
