Fantasy Worlds Vertical Triptych

Goal: Create an ultra-detailed cinematic fantasy triptych showing three separate dream worlds side by side in tall vertical panels: {argument name="left world" default="an underwater Atlantis city with whales and glowing jellyfish"}, {argument name="center world" default="a cherry blossom mountain temple above clouds at sunset"}, and {argument name="right world" default="an alien icy planet landscape with a ringed planet and astronaut"}. Canvas: Tall portrait image, approximately 9:16 aspect ratio, divided into exactly 3 equal vertical panels with clean straight borders and no text. Layout: Use exactly 3 panels. Panel 1 on the left is a luminous underwater fantasy scene. Panel 2 in the center is a warm romantic East Asian mountain vista. Panel 3 on the right is a cold cosmic science-fiction landscape. Each panel should feel like a full standalone poster but align seamlessly as a single panoramic vertical triptych. Left panel details: A grand submerged fantasy city built into cliffs and arches, glowing turquoise-blue water, beams of sunlight pouring down from the ocean surface, coral reefs and rock ledges in the foreground, ornate domed towers and bridges in the middle distance. Include exactly 2 large whales swimming near the upper half, many small tropical fish, and several translucent glowing jellyfish, with the largest jellyfish near the lower left foreground. Mood: magical, deep-sea, bioluminescent, awe-inspiring. Center panel details: A serene Chinese-inspired mountain temple scene at sunrise or sunset, filled with pink cherry blossoms. A dark wooden pavilion roof and balcony occupy the left foreground, with hanging lanterns. A lone woman in a flowing white robe sits on a cliff edge facing the misty landscape, long black hair trailing behind her. Below are steep karst mountains, cloud seas, waterfalls, and small pagodas receding into the distance. Cherry blossom branches arch across the top, and pink petals drift through the air. Mood: tranquil, poetic, ethereal, warm peach and rose lighting. Right panel details: A snowy alien mountain world under a star-filled sky. A small astronaut in a spacesuit stands on a jagged snowy cliff in the lower foreground, looking toward a frozen lake and distant mountains. Above the horizon is a huge blue ringed planet dominating the sky, with visible rings sweeping diagonally across the panel. Include exactly 4 smaller moons or planets around it, plus a bright Milky Way band and a few shooting stars. Mood: vast, lonely, epic, cosmic exploration. Visual style: Hyper-detailed fantasy concept art, cinematic lighting, high dynamic range, sharp foreground detail with atmospheric depth, glowing highlights, volumetric light rays, dreamy color grading. Left panel uses cyan, teal, and deep blue; center panel uses pink, peach, lavender, and gold; right panel uses navy, icy blue, white, and violet. Make the whole image polished, vertical, immersive, and suitable as a high-resolution wallpaper. Constraints: No captions, no logos, no watermark, no extra panels, no duplicate astronauts, no modern buildings in the center panel, no land animals in the underwater panel. Keep the composition balanced with strong vertical depth in all 3 panels.
