Create a 6-8 second vertical action video based on a reference image or brief for [ADULT_RUNNER] moving across a neon city rooftop at night. Use a polished animated action style with cel-shaded highlights, wet rooftop reflections, colorful billboard glow, and a readable skyline depth layer. Start with a low-angle tracking push as the runner accelerates along a rooftop edge. Cut into one controlled vault over a ventilation unit, then a short gap jump to the next roof with believable body weight, foot placement, and landing compression. Let the camera follow close behind and slightly below, adding speed lines or light streaks only as subtle motion accents. End with the runner sliding to a safe stop beside a rooftop sign, turning briefly toward camera while the city lights pulse behind them. Keep the same adult runner, outfit, hair shape, shoe color, rooftop layout, lighting palette, and physics throughout. Avoid youth-coded styling, sexualized framing, weapon threats, direct violence, impossible mid-air flips, broken limbs, warped hands, face drift, jump-cut teleporting, unreadable silhouettes, heavy shake, text overlays, logos, or sudden scene changes.
