Pixel Art Evolution Timeline

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

First, reasoning is conducted around {argument name="theme" default="Western Art Development"} to determine: the Chinese and English titles of the theme, the earliest and most recent historical periods covered, the initial and ending stage labels, as well as 3-5 key evolutionary stages and their respective symbolic elements and color schemes.

Then, an equidistant "Evolution Museum" is constructed with the theme "{argument name="theme" default="Western Art Development"}", with each exhibition hall area representing an evolutionary stage, and spatial advancement representing the evolution of time. Uses a standard equidistant viewing angle (2:1), offering rich depth of layers and smooth transitions. Each stage is divided into 3-5 symbolic elements strongly associated with the theme, and distinctive colors suggest the passage of time. Incorporate bilingual pixel font titles in the scene: Chinese "[Topic Chinese] Evolution History" and English "EVOLUTION of {argument name="theme" default="Western Art Development"}", plus bilingual subtitles for the start and end stages and key time point markers. The overall style is professional and visually impactful, suitable for academic analysis and comparative visualization, with direct image output.
