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.

生成一张【超宽城市系统科普剖面长卷】，单张完整图片，不要拼图，不要多宫格，不要分栏，横版 3:1。

主题：【城市地下系统 / 机场运行系统 / 医院功能系统 / 港口物流系统 / 自定义系统】
标题：【填写科普标题】
核心内容：【填写空间结构、功能分区、运行流程】
信息模块：【控制在 6–8 个】
风格：【高级科普展板 / 系统剖面信息图 / 图文并茂知识可视化】
配色：【填写主色调】

画面重点是把复杂系统的表层、内部结构、功能分区和运行流程一次性讲清楚。
图为主，文为辅。文字只用短标签、模块名、功能词和一句极短说明，不要长段落，不要密密麻麻。

可以加入少量编号、箭头、流程线、细线标注和图例栏，让观众能看懂系统如何运转。

整体像展馆科普长卷、城市系统信息图、PPT 提案中的高级剖面图。

避免文字过满、信息杂乱、拼图感、多宫格、普通风景图、低清晰度。
