积木字体概念设计海报

Generate a "LEGO Brick Typography Concept Poster".

Please design an original brick-style font based on the theme, do not use the official LEGO logo. The main title is assembled from real plastic brick modules, with studs, thickness, shadows, and splicing structures. Automatically generate a core visual metaphor based on the theme meaning, and turn it into a premium design exhibition poster: clean white space, grid layout, infographic logic, concept board structure. The image includes the main title, concept graphics, font samples, module structures, color legends, and fine line annotations. The overall look is premium, restrained, modern, with a collectible poster feel, not like a children's toy advertisement. The aspect ratio is automatically selected based on the theme.
