"positivePrompt": "Inside an abandoned retro-futurist planetarium, the camera glides slowly forward between dusty rows of seats toward a gleaming star projector at center stage. Sunbeams angle through cracked high windows while fine dust swirls in the air. Across the dome, constellations begin to rotate and drift, casting moving celestial patterns over the walls and floor. Loose paper charts flutter gently, tiny motes sparkle, and the atmosphere feels nostalgic, mysterious, and expansive. Highly cinematic motion, subtle parallax, realistic lighting, elegant pacing, richly detailed environment.",

"positivePrompt": "Animate a whimsical fantasy scene guided by the three reference images: keep the masked acrobat and the mechanical donkey as the primary recurring subjects, placed within the dune-side puppet stage environment. The acrobat steps onto the worn wooden platform, ribbons fluttering in the dry breeze, while the donkey trots in playful circles, kicking up dust and making the tassels sway. Camera begins with a wide establishing shot, then gently pushes closer as the acrobat performs a graceful spin and bows toward invisible spectators. Fabric, banners, and loose stage curtains ripple naturally. The donkey tilts its head, stamps a hoof, and gives a lively, charming reaction. Rich golden light, cinematic motion, expressive body language, coherent staging, polished fantasy realism.",
