Then the camera rises up into a high-angle overhead shot of the courtyard: mowed into the grass in dry straw-colored lettering, SEEDANCE on top, 2.5 centered below it, and the Comfy logo underneath with clear space between 2.5 and the logo, 16:9.`

 const CITY_PROMPT = `Cool blue dusk lighting at the start, the same four people sitting and standing outside a café on a city sidewalk, warm lit windows behind them, chatting and laughing, drinking coffee, holding their same general positions but full of lively, animated physical movement — leaning in and back, gesturing broadly with their hands, shifting in their seats, turning to look at each other, genuinely active and expressive rather than mostly still. Partway through the shot, the scene cuts hard and instantly to a new setting with a fun, playful, almost cheeky snap — no blend, no dissolve, just a sudden, bouncy pop-cut, like a magic trick — the same four people now in warm, golden late-afternoon sunlight, seated in the same relative positions at a charming French bistro with a green awning, colorful flower pots, warm string lights, and cobblestone underfoot. No additional or new people appear at any point — only the original four throughout. The instant the cut happens, all four people react with visible confusion — pausing mid-gesture, glancing around at their unfamiliar new surroundings, exchanging puzzled looks with each other, one or two double-taking or squinting at the sudden change in light, before their conversation slowly resumes. Ambient café chatter and city sounds abruptly cut and restart at the pop-cut moment, a beat of surprised murmurs and puzzled “huh?” reactions, followed by a bright, playful whoosh-pop sound and a cheerful little musical sting marking the fun, sudden transition.
 
 Cool blue dusk lighting, warm amber glow from building windows and streetlights against a cooling blue sky, moody late-afternoon color grade. A narrow city street with brick buildings, fire escapes, and a crosswalk, an exact, fixed number of pedestrians going about their day — no additional or duplicate people appear at any point during the shot. A single white 3D cursor, matte and solid with no glow, no light emission, and no trail of any kind, flies around energetically for the entire shot, remaining visible in every frame from start to finish — it never fades, disappears, or drops out of frame for even a moment. It moves toward a specific person or object, slows and hovers directly over it, and clicks — a clear, precise contact moment. Only at the exact instant of that click does the touched person or object transform into something beach-related — sunglasses, inflatable rings, beach balls, sandcastles, surfboards, tropical drinks — popping into place immediately upon contact, never before it. After each transformation completes, the cursor moves on to its next target and repeats the same hover-then-click sequence, each transformation strictly triggered by its own individual click rather than happening on its own. Fast, lively camera movement following the action. Upbeat, playful sound design — clicks, pops, whooshes, and cheerful ambient chatter and laughter as people react to their new beach gear.
