A futuristic cityscape at dusk, with towering skyscrapers and neon-lit streets reflecting off a rain-soaked pavement. A lone hacker, dressed in black leather jacket and ripped jeans, stands atop a dumpster bin, gazing out at the sprawling metropolis. The air is thick with mist, illuminated by flickering LED billboards. In the background, a giant holographic advertisement for 'NeuroSpark' glows bright blue.
