Contour Universe Narrative Poster Prompt for Sora 2

Generate a high-aesthetic "Contour Universe / Collectible Narrative Poster" based on [Theme]. Do not limit the canvas to a fixed object or common container; do not default to bottles, hourglasses, glass domes, or pocket watches. Let the AI choose the most fitting, symbolic, and visually powerful main contour 鈥?it could be an object, building, gate, tower, archway, dome, stairwell, corridor, statue, side profile, eye, palm, skull, wing, mask, mirror, throne, ring, crack, light curtain, shadow, geometric structure, spatial cross-section, stage frame, or abstract symbol. The core concept is not simply putting a world inside an object, but letting a complete thematic universe naturally grow within, inside, upon, at the boundaries of, or fused with this symbolic contour. The contour must be clear, elegant, and recognizable, occupying the central compositional position. Inside the contour, auto-generate a complete narrative world strongly tied to the theme 鈥?rich, layered, with clear visual hierarchy. Style: collectible movie poster composition, premium narrative visual design, dreamy watercolor texture with print quality, paper grain, edge dry-brush marks, slight bleeding, atmospheric perspective, soft fog effects, volumetric light, large negative space. Quality: the result should look like a designer-completed premium collectible visual work, not a generic AI output.
