+## 3. 配置说明
 
-- `OPENAI_API_KEY`：AI 改写能力。
+- `AI 模型配置`、`公众号 AppID/Secret`：由用户在“账号与模型”页面录入，不再依赖 `.env`。
-- `OPENAI_BASE_URL`：可选，兼容第三方网关。
-- `OPENAI_MODEL`：默认 `gpt-4.1-mini`。
-- `WECHAT_APPID` / `WECHAT_SECRET`：公众号发布必填。
-- `WECHAT_AUTHOR`：草稿默认作者名。
 - `IM_WEBHOOK_URL`：IM 推送地址（飞书/Slack/企微等）。
 - `IM_SECRET`：可选签名。
 - `AUTH_DB_PATH`：账号数据库文件路径（SQLite）。
 - `AUTH_SESSION_TTL_SEC`：普通登录会话时长（秒）。
 - `AUTH_REMEMBER_SESSION_TTL_SEC`：勾选“限时免登”时的会话时长（秒）。
-- `AUTH_PASSWORD_RESET_KEY`：忘记密码重置码（用于“用户名+重置码”找回，默认 `x2ws-reset-2026`，建议改掉）。
 
 ## 4. 说明
 
-- 未配置 `OPENAI_API_KEY` 时，系统会使用本地降级改写模板，便于你先跑通流程。
+- 未配置用户级 AI 模型时，改写接口会提示先去“账号与模型”页面完成配置。
 - 建议发布前人工复核事实与引用，避免版权和失真风险。
 - 登录页支持“限时免登”，设置页支持修改密码；忘记密码页支持通过“用户名 + 重置码”重置密码。
