Generate an 8-10 second video prompt for a pastel symmetry visual teaser. Build it as a reusable video brief with three concrete beats: open by establishing the subject, mirrored layout, and soft color world; move into the main reveal, pattern shift, or camera drift with a clear camera path; end on a stable hero frame that can work for a landing page preview, product showcase, or social cutdown. Keep the surreal or stylized idea grounded through concrete beats, controlled camera motion, consistent scale, and visual rules that prevent random symbols from overtaking the concept. Specify pacing, lens feel, camera distance, lighting, motion blur, and continuity rules so the output stays readable. Keep all subjects, props, locations, text, and logos editable. Avoid real brand names, celebrity references, fixed IP, readable signage that cannot be changed, unsafe action, sudden teleport cuts, inconsistent scale, warped anatomy, and unrelated extra scenes.
