+ * generated/<id>} URL can be embedded directly as {@code ![](url)} in a
+ * gzh_package Markdown body.
+ *
+ * <p>Security: only relative in-app paths ({@code /chat}, {@code /channels}, …)
+ * are allowed — no scheme/host, so the tool cannot be aimed at arbitrary hosts
+ * (no SSRF). The injected token is a normal user token scoped to whoever is

+# 微信公众号平台规范与实操要点
+
+写公众号图文时，除了"写得好"，还要"合平台规矩、贴移动端阅读、能被打开"。以下是真实运营里绕不开的硬约束和经验，成文/配图/排版/交付时逐条对照。
+
+## 1. 封面图规范（尺寸是硬要求）
+
+- **头条大图 / 顶部封面**：比例 **2.35 : 1**，建议 **900×383** 或 **1080×460** px。这是文章顶部那张大图。
+- **分享小图 / 朋友圈封面 / 次条图**：比例 **1 : 1**（正方形），建议 **≥ 500×500** px。这是分享到聊天、朋友圈时显示的缩略图。
+- 封面上的**文字要大、要少**——缩略图在手机上很小，一行主标题 + 一句副标题足矣，别塞满字。
+- 用 `image_generate` 出头图时 `aspectRatio=landscape`（近似 2.35:1）；`gzh_package` 会把封面放进文章头部。
+
+## 2. 标题（打开率的命门）
+
+- 后台标题上限 **64 字**，但**强烈建议精炼**（15–30 字最佳）。订阅号在"订阅号消息"里是折叠列表，**读者先看到的往往只有标题**。
+- 好标题带**具体信息 / 数字 / 悬念 / 利益点 / 情绪**，标题和正文**必须一致**——标题党、夸大、"震惊体""速看体"、满屏感叹号会被平台**限流**。
+- 反例：`震惊！！！99% 的人都不知道的秘密`。正例：`我用这 3 个方法，把每天的碎片时间省出了 2 小时`。
+
+## 3. 摘要（digest，别浪费）
+
+- 摘要上限 **120 字**；**不填会自动截取正文前 ~54 字**（常常截得很尴尬）。
+- 摘要显示在**分享卡片、部分历史入口**。**手动写摘要**，用它补一句标题没说完的钩子，别让系统乱截。
+- `gzh_publish` 的 `digest` 参数就是它；不传会自动从正文派生。
+
+## 4. 正文排版（微信编辑器习惯）
+
+- **字号**：正文 15px（最常用）或 16px；小标题 16–17px 加粗。
+- **行间距** 1.75–2.0；**段间距**要留白。公众号习惯**首行不缩进**，靠段间距分段。
+- **字色**：正文用 `#3f3f3f` / `#333`（不用纯黑 `#000`，太硬）；重点色**不超过 2–3 种**（品牌色 + 黄底标重点足够）。
+- **图片**宽度自适应（100%）；图注用小字、灰色、居中。
+- **每段 3–4 行以内，多用短句**——手机一屏能读完一个意群。首屏（首图 + 前 3–4 行）决定读者跳不跳出。
+- `gzh_package` 已内置这套内联样式；手写 HTML 时对齐这些数值。
+
+## 5. 诱导红线（微信平台规则，**比广告法更容易封号**）
+
+这是真实运营最常踩的坑，和《广告法》是两回事——属于**微信运营规范**，违规会**限流、删文、扣原创分、封号**：
+
+- **诱导分享**（严禁）：用利益或胁迫诱导转发，如"**分享到朋友圈截图领取**""**集赞 XX 个送**""**为 XX 助力**""**分享后解锁全文**""**不转不是 XX**"。
+- **诱导关注**（严禁）：**强制/利诱**才能看全文或领资料，如"**关注公众号才能看后续**""**关注领取完整版**"。**正常引导关注可以**（"觉得有用就关注一下"），**强制/利诱不行**。
+- **外链 / 二维码跳转**：正文**不能直接放外部网址**跳到淘宝、外部下载、非白名单站点；诱导"长按识别二维码加个人微信/关注他人号"批量导流有风险。合规外链走文末"阅读原文"（白名单或公众号文章链接）。
+- **标题党 / 内容不符**：标题夸大、与正文不符 → 限流。
+- **抄袭 / 洗稿**：被原创方投诉 → 删文 + 扣信用分。
+
+> 引导互动要用**话术**而非**利诱**：`觉得有帮助，欢迎点赞、在看、转发，也欢迎关注` ✅；`转发集赞 20 个抽奖` ❌。
+
+## 6. 发布频次与时机
+
+- **群发频次**：订阅号**每天 1 次**（一次可含多条图文合并推送）；认证服务号**每月 4 次**。
+- **高打开时段**（视受众调整）：早 **7:00–9:00**（通勤）、午 **12:00–13:30**、晚 **20:00–22:30**（黄金）、睡前 **22:30–23:30**。上班族偏早晚通勤，学生/宝妈偏午间和晚间。
+- **固定节奏**（如每周二四六早 8 点）有助于养成读者打开习惯。
+- 定时推送可用「每周公众号入草稿箱」这类 Cron 模板生成，人工核对后发。
+
+## 7. 原创与互动机制
+
+- **声明原创**（账号需已开通原创功能）：可获**原创标、留言、赞赏、被转载保留出处**。原创内容平台推荐权重更高。
+- 文末**引导互动**：点赞 / 在看 / 留言 / 转发 / 关注——用真诚话术。**主动引导留言并精选**能提升互动权重。
+- **搜一搜 / SEO**：标题、正文前 100 字合理布局关键词，有助于被"搜一搜"收录，带来长尾流量。
+
+## 8. 敏感行业额外合规
+
+- **医疗 / 保健 / 药品 / 保健品**：不得宣称疗效、治愈、抗癌等（见 `compliance_checklist.md`），且多需资质。
+- **金融 / 投资 / 理财**：不得承诺收益、保本、稳赚。
+- **教育 / 培训**：不得承诺"包过""保分""名校保录"。
+- 这些行业发文前务必让用户确认资质与措辞。
+
+## 交付前自检（把上面浓缩成一句话清单）
+
+- [ ] 封面 2.35:1（头图）/ 1:1（分享图），文字大而少
+- [ ] 标题 ≤30 字、不标题党、与正文一致
