Isometric Pixel Art Evolution Museum

Create an ultra-high detail isometric pixel art timeline illustration (3:4, 4K) that blends detail density, symbolism, and metaphor. The user-specified theme is "theme". First, perform reasoning around theme to determine: the bilingual Chinese and English titles, the earliest and most recent historical periods covered, the starting and ending phase labels, and 3-5 key evolution stages with their respective symbolic elements and color schemes. Then construct an isometric "Evolution Museum" themed around "theme", where each gallery area represents an evolution stage, and spatial progression represents temporal evolution. Use a standard isometric perspective (2:1) with rich depth layers and smooth transitions. Assign 3-5 symbolic elements strongly associated with the theme to each stage, using differentiated colors to suggest the flow of time. Incorporate bilingual pixel font titles in the scene: Chinese "[Theme in Chinese] Evolution History" and English "EVOLUTION OF theme", along with bilingual subtitles for the start and end phases and key time node markers. The overall style should be professional and visually striking, suitable for academic analysis and comparative visualization, directly generating the image.
