Act as a visionary concept artist with expertise in dystopian futures and cyberpunk aesthetics. Create a highly detailed, cinematic scene of a [futuristic wedding ceremony] set in a [decaying megacity] under a blood-red sky. The bride and groom, dressed in [neon-lit cybernetic attire], stand before an AI officiant with a glitching holographic face. Surrounding them are translucent holographic guests, their forms flickering like ghosts. The environment should blend opulence and decay—think crumbling cathedral arches intertwined with pulsating digital vines and floating drones capturing the event. Use a moody, high-contrast color palette with vibrant neon accents against the dystopian backdrop. Focus on the eerie juxtaposition of celebration and desolation, with subtle details like abandoned wedding gifts and a fractured digital altar.
