+# blog-5l：后台预览一致性 + 排版提醒 + 瞬间置顶/隐藏 - 完成总结
+
+## 交付结论
+- 结果：完成
+- 完成时间：2026-11-05 10:03
+
+## 假设回顾
+### 已验证假设
+- 预览窗格是 CMS 内部管理的文档，官方 registerPreviewStyle 是唯一稳定注入口（MutationObserver 手注会被重渲染冲掉且升级易碎）
+- 预览目标是「类效果可见」（颜色对、字体对、基础排版近似），不追求像素级还原
+
+### 仍未完全验证的假设
+- 无
+
+## 交付范围
+### 已交付
+- task_0001 预览样式注入
+- task_0002 编辑提醒
+- task_0003 瞬间置顶/隐藏
+
+### 未交付
+- 无
+
+### 偏差说明
+- 无
+
+## 简化决策
+### 保持简单的关键选择
+- 最简可行：一个新脚本 preview-style.js + 三处既有文件小改（typography-classes 加 css 字段、typography-editor pattern 放宽、config.yml hint/开关）+ moments 三点改（schema/MomentsPage/config.yml）+ 一条置顶示例数据 + E2E 断言更新
+- 暂不引入：常驻样式速查面板、预览明暗主题切换
+- 不做的抽象：通用「字段级 hint 生成器」（hint 手写三处即可，量小不值得抽）
+- 范围级别：package
+- 变更对象：后台静态资源（public/admin）与瞬间列表渲染（MomentsPage）
+- 快速检查：`pnpm astro build` + `python3 scripts/build-perf/config-check.py .`
+- 集成检查：E2E 59 项 + content-lint 0/0/0 + 产物 grep（moments 首卡 pin 徽标、admin 三脚本接线序）
+- 全项目检查：生产部署后人工核验后台预览显色显字体；**升级条件**——仅当改动触及 BaseLayout 字体注入或 build 链时才升级全站回归，本包不涉及
+- 升级触发：后台预览为独立资源面，升级为「后台人工核验」即可
+
+### 本轮明确不做的内容
+- Sveltia bundle 升级与魔改；预览像素级还原；moments 单条页面 / RSS / sitemap 变化
+
+## 变更边界
+### 本轮主要改动模块
+- 见 tasks.md 的 boundary 记录
+
+### 明确未触碰的区域
+- Sveltia bundle 升级与魔改；预览像素级还原；moments 单条页面 / RSS / sitemap 变化
+
+## 验证证据
+### 备注
+- 机器证据：runs.jsonl（见验证范围的机器验证率）
+
+## 验证范围
+- 级别：package
+- 机器验证率：3/3
+- 规则：check 与 done 复用该范围；只有记录升级触发时才执行全项目检查
+
+## 哲学生效证据
+### 行为成效回填
+- Development Record 行为门禁通过
+
+### 一致性门禁回顾
+- 验收面（checklist 或成功标准）已通过
+
+## Git 记录
+- 日期时间：2026-11-05 10:03
+- 范围：blog-5l：后台预览一致性 + 排版提醒 + 瞬间置顶/隐藏
+- 功能：task_0001 预览样式注入；task_0002 编辑提醒；task_0003 瞬间置顶/隐藏
+- 操作：提交 / 推送
+- 成效：Development Record 行为门禁通过
+- 提交：pending local commit
+- 提交区间：c5889f960b94a70c61b7c31d13e3e4be4cacaaf8..c5889f960b94a70c61b7c31d13e3e4be4cacaaf8
+- 推送：not-run (push stage follows commit)
+
+## AGENTS.md 增量提议
+```diff
+后台编辑体验三件套：预览窗格显色显字体（registerPreviewStyle 官方口子 + 切片字体按需取片）、编辑字段排版速查提醒、瞬间置顶/隐藏真字段（对齐 posts 契约）。
+```
+
+## 被拒绝的扩展提议

+## 门禁证据

+# blog-5l：后台预览一致性 + 排版提醒 + 瞬间置顶/隐藏
+
+<!-- spec-format: 2 -->
+
+- **slug**: 2026-11-05_blog-5l-admin-preview-moments
+- **日期**: 2026-11-05
+- **状态**: 进行中
+- Git integration branch：`spec/2026-11-05_blog-5l-admin-preview-moments`
+- 证据协议：evidence: runs
+- **提案**: 后台（Sveltia CMS）编辑 markdown 时的预览窗格不渲染排版类（font- 字体、c-/ink- 颜色看不到效果），且编辑时缺少「能用哪些字体/颜色」的提醒；瞬间（moments）需要与文章一致的置顶/隐藏能力。三件事合成一包：预览注入站点排版样式（官方 `CMS.registerPreviewStyle`）、hint/文档提醒、moments pinned/hidden 真字段契约。
+
+## 1. 问题定义
+- **项目目标**：后台编辑 markdown 时预览窗格直接显色/显字体（与真实页面一致），编辑时能看到可用字体/颜色的提醒；瞬间获得与文章一致的置顶/隐藏能力。
+- **目标用户**：站长（编辑体验与内容管理）；读者不受影响（仅瞬间排序/可见性语义对齐）
+- **核心价值**：所见即所得消灭「写完发布才发现样式不对」的往返；moments 与 posts 的管理语义统一，降低心智负担
+
+## 2. 假设与待确认
+
+### 2.1 已确认事实
+- Sveltia 0.252.0（本地 pinned bundle）含 `registerPreviewStyle`（raw 字符串/URL 两态，支持 collection 作用域）——bundle 内已核实校验逻辑
+- 已有「排版」inline 编辑器组件（Insert ▸ 排版，typography-classes.js 清单 + 自建选择面板：字体实样 + 色卡）
+- posts 已有 pinned/hidden 真字段 + post-visibility 单一事实源；moments 排序在 MomentsPage.astro 内联（唯一消费点）
+- 自托管字体切片落 public/fonts/<family>/fonts.css（unicode-range 按需取片），路径稳定可被后台引用
+
+### 2.2 关键假设
+- 预览窗格是 CMS 内部管理的文档，官方 registerPreviewStyle 是唯一稳定注入口（MutationObserver 手注会被重渲染冲掉且升级易碎）
+- 预览目标是「类效果可见」（颜色对、字体对、基础排版近似），不追求像素级还原
+
+### 2.3 待确认问题
+- [x] 预览注入走官方 registerPreviewStyle，不走 iframe hack（0.252.0 已核实存在）
+- [x] 真字体预览走切片 CSS（unicode-range 按需取片），不在后台整包加载 TTF
+- [x] moments 置顶多选允许（与书架/文章口径一致）；隐藏 = 真字段过滤，无 legacy tag 兼容
+
+### 2.4 可选解释与取舍
+- 提醒做成 hint 速查 + 已有排版面板的入口提示，不做常驻侧栏文档组件（Sveltia 定制面有限，hint 是官方支持的展示位）
+- serif/kai/kuaile 的 CSS 经 Vite ?url 打包成哈希名，后台引不到稳定 URL，预览走字体栈系统回退（近似可见，文档注明差异）
+
+### 2.5 已证伪路径
+- 往预览 iframe 手动注入 `<style>`：预览文档由 CMS 内部管理，注入会被重渲染冲掉、升级易碎——官方 API 存在，必须走官方口子
+
+## 3. 功能范围
+
+### 3.1 核心功能（MVP）
+- [x] T1 预览一致性：preview-style.js 从清单运行时生成排版类 CSS + 富文本基础排版（raw 注入）+ 自托管艺术字体切片 CSS（URL 注入）；pattern 放宽到多类
+- [x] T2 编辑提醒：posts 正文 / moments 文字 / 关于页整页正文三处 hint 补速查；docs/管理台.md 增「预览窗格直接显色/显字体」节
+- [x] T3 瞬间置顶/隐藏：schema 真字段 + 列表过滤排序 + 灰阶 pin 徽标 + 后台开关 + E2E 断言
+
+### 3.2 扩展功能
+- 无
+
+### 3.3 不在范围内
+- Sveltia bundle 升级与魔改；预览像素级还原；moments 单条页面 / RSS / sitemap 变化
+
+## 4. 最小实现路径
+- 最简可行：一个新脚本 preview-style.js + 三处既有文件小改（typography-classes 加 css 字段、typography-editor pattern 放宽、config.yml hint/开关）+ moments 三点改（schema/MomentsPage/config.yml）+ 一条置顶示例数据 + E2E 断言更新
+- 暂不引入：常驻样式速查面板、预览明暗主题切换
+- 不做的抽象：通用「字段级 hint 生成器」（hint 手写三处即可，量小不值得抽）
+
+### 5.1 验证策略
+- 范围级别：package
+- 变更对象：后台静态资源（public/admin）与瞬间列表渲染（MomentsPage）
+- 快速检查：`pnpm astro build` + `python3 scripts/build-perf/config-check.py .`
+- 集成检查：E2E 59 项 + content-lint 0/0/0 + 产物 grep（moments 首卡 pin 徽标、admin 三脚本接线序）
+- 全项目检查：生产部署后人工核验后台预览显色显字体；**升级条件**——仅当改动触及 BaseLayout 字体注入或 build 链时才升级全站回归，本包不涉及
+- 升级触发：后台预览为独立资源面，升级为「后台人工核验」即可
+
+## 6. 成功标准与验证方式
+- [x] 后台预览排版类显色/显字体 -> verify: task_0001（manual: 生产后台人工核验，代码面由 task_0001 断言覆盖）
+- [x] 编辑字段 hint 含字体/颜色速查与排版面板入口 -> verify: task_0002
+- [x] moments 置顶排序 + hidden 过滤 + 后台开关 + pin 徽标 + E2E 全绿 -> verify: task_0003
+
+## 7. 关联与风险
+- 前序：5h T1（posts 置顶）、5j T3（页面文案 hint 体系）、5i T9（字体切片管线）
+- 风险：registerPreviewStyle 的 URL 模式对预览文档的 base URL 解析若与预期不符，退路是把切片 CSS 也 fetch 成文本走 raw 注入（同一 URL，语义等价）
+- 本包不动：热力图（另线预览选型中）

+ * 后台预览一致性（5l T1）：把站点排版效果注入 Sveltia 预览窗格。
+ *
+ * 现状问题：markdown 里的排版类（font- 字体、c-/ink- 颜色）在预览里是素文本——
+ * 类名随 DOM 保留（typography-editor 的 toPreview 输出带 class），但预览
+ * 文档没有站点 CSS，颜色字体全部不可见。
+ *
+ * 方案（官方口子，勿改成 iframe hack——见 spec 5l §2.5）：
+ *  1. 基础富文本排版 + 全部排版类 CSS 从 window.TYPOGRAPHY_CLASSES
+ *     **运行时生成**（清单单一事实源：typography-classes.js 改一处，
+ *     选择面板与预览自动同步），raw 模式注入；
+ *  2. 自托管艺术字体挂切片 CSS（public/fonts/<family>/fonts.css，
+ *     unicode-range 按需取片——预览里只拉用到的字所落在的切片，不整包）。
+ *
+ * serif/kai/kuaile 的 CSS 经 Vite ?url 打包成哈希名，后台引不到稳定 URL，
+ * 预览走字体栈里的系统回退（Kaiti SC/Songti）——近似可见，文档已注明。
+ * 加载顺序：须在 typography-classes.js 之后、CMS init 之前（index.html 固定序）。
