// 構建腳本：esbuild 產出 ESM / IIFE / CSS；d.ts 由 `tsc --emitDeclarationOnly`
// 另行產出（見 package.json scripts）。
//
//   dist/juzhen.mjs       ESM，供打包器／TypeScript／jsdom 測試。
//   dist/juzhen.iife.js   IIFE，全域 `Juzhen`，原生 <script> 直跑；額外掛
//                         `globalThis.createCjkAutospace` 別名（v1 相容消費端）。
//   dist/juzhen.css       合併之樣式（css/juzhen.css 之 @import 展開）。
