從零重寫之第一垂直切片（依 ARCHITECTURE.md 契約），涵蓋並超越 v1 全部功能。

核心基座（src/core）：unicode 字元表＋標點子類＋字形側位；locale 語言與
全角／開明政策（全域 lang.style ＋逐 lang policy）；dom（jz-* 工廠＋可還原
標記）；finder 遍歷引擎（avoid／scope.include／邏輯 run／pill 鄰字／分塊閘）；
pass 聚合管線。

功能 pass（src/typeset）：
- spacing：中西間隙採 margin 模型——包裹邊界左側字、以 margin-right 留隙，
  不注入空白字元（textContent 完全不變、複製緊湊、justify 不暴增、不撐框、
  行首乾淨）。含跨樣式邊界、pill、原檔空格移除。
- gapTrim（lineedge）：layout pass，行末去隙，修正 justify 右緣內縮。
- longword：長英文詞 <span lang> + hyphens。
- jiya：標點 charify + 全角／開明／半角（全域 + 逐 lang）；半形以字型 OpenType
  halt 渲染（按字形正確定位、不重疊，居中字形 ！？ 與繁體 locl 句逗點號皆正確）；
  行內連續擠壓。
- jinze：行首行末避頭尾（閉類／點號綁前字、開類綁後字，以詞元為邊界、長引文
  中段可斷）；亦為 justify 綁定載體。
- lineedge：行端擠壓 layout pass（括號引號；ResizeObserver 重算，瀏覽器專用）。

§8 justify：jz-char inline-block 原子，句末標點單份間距。
v1 相容層（compat/v1）：createCjkAutospace().apply 映射，IIFE 全域別名。
構建：esbuild → ESM／IIFE／CSS；tsc → d.ts。測試：39 個 jsdom 案例。
demo：簡繁並列＋justify＋強制繁體開明＋標點寬度量測，載 Noto webfont 作參考
（擠壓依賴字型 halt）。間隔號 · 不觸發中西間隙；200% 等詞元不被禁則切斷。

+## 安裝與構建

+npm install
+npm run build   # esbuild → dist/juzhen.{mjs,iife.js,css}；tsc → dist/index.d.ts
+npm test        # jsdom DOM 正確性測試
+```
+
+產物（`dist/`，已入庫）：
+
+| 檔 | 用途 |
+|---|---|
+| `dist/juzhen.mjs` | ESM，供打包器／TypeScript |
+| `dist/juzhen.iife.js` | IIFE，全域 `Juzhen`，原生 `<script>` 直跑 |
+| `dist/juzhen.css` | 合併樣式（**必須引入**，視覺尺寸全在此） |
+| `dist/index.d.ts` | TypeScript 型別宣告 |
+
+---
+
+## 用法
+
+### 原生 `<script>`
+
+```html
+<link rel="stylesheet" href="dist/juzhen.css">
+<script src="dist/juzhen.iife.js"></script>
+<script>
+    const jz = Juzhen.createJuzhen({ scope: { include: ".prose" } });
+    jz.render();          // 對 document.body 套用（僅命中 .prose 子樹）
+    // jz.revert();        // 還原
+</script>
+```
+
+### ESM／TypeScript
+
+```ts
+import { createJuzhen } from "cjk-autospace";
+import "cjk-autospace/css";
+
+const jz = createJuzhen({ lang: { default: "zh-Hant" } });
+jz.render(document.querySelector("main"));
+```
+
+**JS 與 CSS 缺一不可**：JS 只注入 `jz-*` 結構，所有視覺尺寸（間隙寬度、擠壓量、
+`justify` 原子化、字體堆疊）都在 `juzhen.css`。
+
+---
+
+## 切片 1 已實作功能
+
+| 功能 | 說明 |
+|---|---|
+| **中西間隙** `spacing` | CJK↔西文邊界插入 copy-clean 之 `jz-hws`（`user-select:none`，剪貼板跳過）。含跨樣式行內邊界與 `code`／`kbd` pill 邊界。 |
+| **長英文詞** `longWord` | `[A-Za-z]{6,}` 包入 `<span lang="en">`，配合 CSS `hyphens:auto` 原生斷詞（DOM 無連字符 → 複製不污染）。 |
+| **標點擠壓** `jiya` | 標點 charify 為 `jz-char`＋`bd-*` class。三機制：①baseline 政策（全角式不擠／開明式擠句內點號＋括號引號／半角式全擠）；②行內連續擠壓（相鄰標點對向側收）；③行端擠壓（`lineedge` layout pass）。半形以字型 `halt` 渲染（按字形正確定位，居中字形如 `！？`／繁體 `。，` 不重疊；不依賴 `text-spacing-trim`）。 |
+| **禁則** `jinze` | 行首行末避頭尾：閉類／點號綁前一字（不置行首）、開類綁後一字（不置行末），只隔離邊界字故長引文中段仍可斷。亦為 `justify` 綁定載體。 |
+| **justify 單份間距** | 每個 `jz-char` 為 `inline-block` 原子項，句末標點只貢獻一份對齊伸縮量。 |
+
+後續（架構已預留，不返工）：標點懸掛、標點修正（簡↔繁）、著重號、注音／Ruby。

+// 既有消費端零改動：
+const cjk = createCjkAutospace({ pillSelector: "code, kbd" });
+cjk.apply(document.body);
+```
+
+IIFE 構建另掛 `globalThis.createCjkAutospace` 別名。**與 v1 之差異**（行為等價、
+不要求逐位一致）：
+
+- 間隙標記由 `<span class="cjk-autospace">` 變為 `<jz-hws class="cjk-autospace">`
+  （仍帶原 class，既有 `.cjk-autospace{user-select:none}` CSS 仍命中）。
+- 標點擠壓由消費端 `font-feature-settings:"halt"` 改為 `juzhen.css` 之負 `margin`
+  （需改用 `juzhen.css`；機制不同，同為開明式「句內點號半形」之效果）。

+## 目視驗證

+`demo/index.html` 載入 `dist/` 產物，簡繁並列、可切 `justify`、附 copy-clean 測試區。
+版面相關結論（justify 單份間距、擠壓視覺量、行端、`inline-block` 基線）須於
+Chrome／Safari／Firefox 三引擎目視核對——jsdom 僅驗證 DOM 結構正確性。
