アイソメトリックピクセルアート進化博物館

Create an ultra-detailed isometric pixel art timeline illustration (3:4, 4K) that blends detail density, symbolism, and metaphor. The user-specified theme is "{argument name="theme" default="Western Art Development"}".

First, reason around "{argument name="theme" default="Western Art Development"}" to determine: bilingual Chinese-English titles, the earliest and latest historical periods covered, start and end stage labels, and 3-5 key evolutionary stages with their respective symbolic elements and color schemes.

Then, construct an isometric "Evolution Museum" themed around "{argument name="theme" default="Western Art Development"}", where each gallery area represents an evolutionary stage, and spatial progression represents temporal evolution. Use a standard isometric perspective (2:1) with rich depth layering and smooth transitions. Assign 3-5 symbolic elements closely related to the theme to each stage, and use differentiated colors to imply the flow of time. Incorporate bilingual pixel font titles in the scene: Chinese "{argument name="theme" default="Western Art Development"}演变史" and English "EVOLUTION OF {argument name="theme" default="Western Art Development"}", as well as bilingual sub-titles for the start and end stages and key timeline markers. The overall style should be professional and visually impactful, suitable for academic analysis and comparative visualization, directly generating the image.
