Node.js project architecture standards for AI-assisted development. Enforces file splitting (<400 lines), config externalization, route modularization, and admin dashboards. Use when creating new Node.js projects, refactoring large single-file codebases, or when AI context window is being consumed by oversized files. Covers H5 games (Canvas/Phaser/Matter.js), data tools (crawlers/scrapers), content platforms, monitoring dashboards, API services, and SDK libraries.

适用于AI辅助开发的Node.js项目架构规范，强制要求文件拆分（小于400行）、配置外化、路由模块化和管理面板集成。适用于新建Node.js项目、重构大型单文件代码库，或因文件过大导致AI上下文窗口超载时使用。涵盖H5游戏（Canvas/Phaser/Matter.js）、数据工具（爬虫/抓取工具）、内容平台、监控面板、API服务和SDK库。
