Create a vertical 9:16 dark sci-fi e-commerce product detail page for a fictional chrome endoskeleton humanoid robot. Use a premium online-shopping product-page layout with a search bar, product hero area, price block, detail modules, feature icons, and usage-scenario cards, but keep all branding fictional and generic. Show the robot in front, side, and back three-view drawings, with polished black-chrome metal, exposed mechanical joints, glowing red sensor eyes, cables, pistons, and precise industrial details. Include sections for product price, structural details, core functions, and usage scenarios such as collection display, film-prop photography, exhibition display, and robotics education. Use a cinematic dark blue and black interface, high-contrast product photography, sharp technical panels, clean Chinese product-page typography, and small icon labels. The design should feel like a believable product showcase page, visually dense but organized, with the robot as the dominant subject. Avoid real platform logos, real brand names, franchise names, copyrighted character names, or official product marks.
