Coral Descent Symphony

Create a cinematic underwater world still as a native exact 4:5 vertical gallery-card composition, adapted from a camera-descent prompt into a single image. The viewpoint feels as if the camera has just plunged through the shimmering ocean surface into a mysterious, colorful sea world, with rising bubbles in the foreground. Show vivid coral reefs spreading like dreamlike castles across the seafloor, gently moving with the current; schools of colorful tropical fish weave through them, their scales catching faint light. Add an elegant great white shark gliding through the middle distance, blue glowing jellyfish farther away in the dark, and a giant sea anemone with soft tentacles in the foreground. Use turquoise-blue water, sunbeams from above, suspended particles, realistic fish motion, coral texture, bubble trails and a sense of orchestral underwater movement. Keep the coral reef, shark, fish schools, jellyfish glow, anemone and water-surface light inside the central safe area. Avoid murky water, horror mood, cartoon style, mermaid focus, giant text, watermark, cropped shark or low-resolution blur.
