Create a polished 15-second 16:9 fictional shoe commercial. Photoreal editorial cinematography. Sound ON. PRODUCT LOCK: a pair of black suede crystal-strap stilettos is exactly the attached pair — black suede pointed stiletto pumps, cream insole, crystal-jewel ankle straps with a dangling crystal, stiletto heel, no back strap on the heel. Photocopy these shoes. Never sneakers. Never ivory runners. Never coral midsoles. SUBJECT: Exactly one adult seen from the waist down. Black tailored trousers or a slim black hem. Same pair of a pair of black suede crystal-strap stilettos on both feet. No other people. No face. LOCATION: One elegant city sidewalk, initially nearly monochrome cool gray. Wet pavement. 0–3s: Extreme low-angle close-up of the right stiletto hovering above wet gray pavement. It lands firmly once. On contact a circular silver-crystal / champagne light wave ripples out across the pavement. 3–9s: Track alongside the legs, two or three deliberate steps in the stilettos. As the wave travels, the gray street and buildings become rich warm color and amber sunlight. Shoes stay physically realistic. Heels click. No floating. 9–12s: Arc around the planted stiletto at ground level while the last gray parts become colorful. Crystal strap sparkles. 12–15s: Clean close product view of the planted black suede stiletto, sharp suede texture, crystal strap, warm backlight, colorful city soft behind. Hold 1.5s. AUDIO: city atmosphere, deep impact on first footfall, original electronic rhythm, no vocals, no songs. No on-screen text. Duration 15s. Aspect 16:9. OPENING: already the shoe above pavement — never a white packshot still.
