<lora:kreaneondinasty:0.5>An enormous white-and-gold articulated cybernetic forearm hangs from visible mechanical supports inside a tall black marble advertising portal. A burgundy velvet sleeve with broad gold floral embroidery covers the upper section. Cyan vertical light strips and large gilded leaf relief frame the installation. Small people look upward from the steps and polished plaza below. Beyond the display, elevated routes and slender futuristic towers glow with magenta architectural light under a deep blue evening sky, with one airborne vehicle above. Dramatic low-angle vertical composition contrasts the oversized product with the surrounding public.
