超宽城市系统科普剖面长卷

Generate an [Ultra-wide City System Science Popularization Cross-section Long Scroll], a single complete image, no collages, no multi-grids, no columns, horizontal aspect ratio 3:1.

Theme: [Urban Underground System / Airport Operation System / Hospital Functional System / Port Logistics System / Custom System]
Title: [Fill in Science Title]
Core Content: [Fill in Spatial Structure, Functional Zoning, Operation Flow]
Information Modules: [Keep between 6–8]
Style: [Advanced Science Popularization Exhibition Board / System Cross-section Infographic / Knowledge Visualization with Text and Images]
Color Palette: [Fill in Main Tone]

The focus of the image is to explain the surface, internal structure, functional zoning, and operation flow of a complex system all at once.
Images as the primary focus, text as the secondary. Use only short labels, module names, functional words, and one extremely short description for text; no long paragraphs, no dense clutter.

A small number of numbers, arrows, flow lines, thin line annotations, and legend bars can be added to let the audience understand how the system operates.

The overall style is like an exhibition hall science long scroll, a city system infographic, or a high-end cross-section diagram in a PPT proposal.

Avoid excessive text, cluttered information, a collage feel, multi-grids, ordinary landscape photos, and low resolution.
