Generate a detail page poster for the aluminum frame hard-shell trolley suitcase based on the provided white-background product images. The background is a light blue-gray gradient rounded easel, with two rows of dark gray titles aligned on the top left: "Aluminum Frame Structure / Sturdy Travel," and a tiny English decorative text placed at the top right; Place a line of description below the title along with a short orange line. The middle section displays a semi-explosive structure of a silver-white aluminum frame suitcase, with wheelsets, tie bars, corner guards, and the box frame surrounding the main body, and a faint large numeric decoration on the back. Three fine leads are marked with "tight frame," "reinforced middle frame," and "smooth wheelset." The product retains a silver-white vertical rib shell, metal frame, black handle, and double wheels, with adjustable corner guards and lock details; The original product lacks clear brand information and does not include the brand or slogan. The font is modern sans-serific, with bold and left-aligned headings, and thin and smooth leads. Avoid overlapping actual load values, standard certification, footnotes, watermarks, and text.
