Design a futuristic, 10-hectare biophilic seaport inspired by a sea creature designed to float. The structure should be a vast, horizontal development with bright (panoramic elevators:1.2) descending to the depths of the sea. The above-water portion should feature organic, flowing lines and parallel accent lines, reminiscent of gills. Its white ceramic façade should reflect the ocean, while the interior should be a serene oasis of natural light and greenery. The port should be a bustling hub of activity. Beneath the surface, a vibrant, technologically advanced underwater city should thrive, prominent neon-colored laser lights and concentric navigation lights.
