Neon Coral Reef on an Alien Cyberpunk Planet

An alien planet's coral reef city glowing with neon cyberpunk lights: coral skyscrapers with chrome surfaces, bioluminescent polyps in magenta, cyan and electric blue; glass tunnels threaded through the reef; holographic signage projected on coral walls; cybernetic fish with LED circuits and drone seahorses patrolling; schools of augmented fish weaving through kelp, algal code trails, and manta ray drones; distant reef-temple skyline visible through crystal-clear water; cinematic neon-noir mood, hyper-detailed photorealism, macro textures on coral, volumetric light; wide-angle underwater panorama.
