Swap one definition JSON and a full document stack appears — loading, saving, building tables, with zero bespoke code. A framework-free Web Component front-end and a zero-dependency spreadsheet engine, backed by a fleet of independent Rust microservices. 换一份定义 JSON，即得完整的单据装载/回存/建表能力，零专属代码。框架无关的 Web Component 前端 + 零依赖电子表格引擎，由一支独立的 Rust 微服务矩阵在后端支撑。
A metadata-driven platform built on framework-free Web Components and a zero-dependency spreadsheet engine.
The runtime portal at /portal/ — page routing, navigation, metadata-driven doc/dict/report workspace, built with UI5 Web Components and Vite 8.
运行于 /portal/ 的门户运行时——页面路由、导航、元数据驱动的单据/字典/报表工作台，使用 UI5 Web Components 与 Vite 8 构建。
Visual HTML page designer at /html/ — drag-drop composition, live preview, form and layout components, CodeMirror integration.
运行于 /html/ 的可视化 HTML 页面设计器——拖拽组合、实时预览、表单与布局组件，集成 CodeMirror。
35 framework-free custom elements: master-slave coordinator, data-set, column model, grids, forms, dict-select, formula editor, KPI cards, dialogs — no React, Vue, or Angular required. 35 个框架无关自定义元素：主从协调器、数据集、列模型、表格、表单、字典选择、公式编辑器、KPI 卡片、对话框——不依赖 React / Vue / Angular。
Shared UI5 + Tabler runtime bundle at /shared/, consumed by both Portal Manager and HTML Designer. Single build, zero duplication.
运行于 /shared/ 的共享 UI5 + Tabler 运行时 bundle，被门户管理器与设计器共同消费。一次构建，零重复。
Three engines, one vision. A clean-room TypeScript front-end engine (<cmx-megasheet>, 335 functions, zero deps), its Rust twin for headless server-side use (335 functions, byte-identical), and cmx-sheetwright — a CLI/HTTP protocol shell that turns the Rust engine into headless Excel.
三引擎，一体系。clean-room TypeScript 前端引擎（<cmx-megasheet>，335 函数，零依赖）、逐字对等的 Rust 无头引擎（335 函数，byte-identical），以及 cmx-sheetwright——把 Rust 引擎变成无头 Excel 的 CLI/HTTP 协议壳。
The platform's back-end is a constellation of independent Rust microservices — each its own workspace, process, and port — all reusing one shared library and one metadata contract. 平台后端是一支独立的 Rust 微服务星群——各自独立 workspace、进程与端口——共享同一套公用库与同一份元数据契约。
