Act as a visionary marine architect with expertise in biophilic design. Create a breathtaking underwater cityscape where buildings are organically grown from living coral reefs, blending seamlessly with the ocean environment. The structures should feature [LUMINESCENT CORAL SPIRES], [GLOWING JELLYFISH LANTERNS], and [FLUID, WAVE-INSPIRED BRIDGES]. The scene should be bathed in ethereal blue-green light, with schools of tropical fish weaving between the towers. Include intricate details like barnacle-encrusted facades, pearl-embedded pathways, and kelp gardens swaying in the currents. The composition should evoke a sense of harmony between advanced civilization and untouched marine beauty, with [A SUBMERSIBLE TRANSPORT SYSTEM] gliding silently through the scene. Render in hyper-realistic 4K with cinematic lighting.
