Act as a cyberpunk underworld architect with expertise in dystopian urban decay. Design a hidden hacker collective lair concealed within an abandoned subway station. The scene should feature [GLOWING NEON SIGNS] flickering with cryptic symbols, [RUSTED TRAIN CARS] repurposed as makeshift workstations filled with holographic displays, and [TANGLED CABLES] snaking across damp concrete floors. Include atmospheric details like steam vents, flickering overhead lights, and shadowy figures hunched over glowing keyboards. The composition should emphasize the contrast between the hackers' vibrant digital world and the decaying industrial environment, using a moody color palette of electric blues, deep purples, and sickly greens. Render in a cinematic 16:9 aspect ratio with dramatic lighting that highlights both the technological and derelict aspects of the hideout.
