    ⚠️ 卡是固定高度 bento，只有 kick / weight 有位置放第二行（`.mc-extra`）；给 fweight/cal/curve 加第二行前
    先重排那笔高度账（`158+10+64=232`，见 `mama-box.css`）。
 
+12. **⚠️ 第 2 条「不造假数据」的唯一登记例外：首页「此刻，孕妈们在做什么」卡（2026-10-01 起）**
+   - 内容：该卡的总人数 / 今日三项 / 匿名动态在**模拟阶段**为 box_app 按规则生成的模拟数字（`GET /pulse`，确定性哈希、不落库、不进任何报表）。
+   - 决策人：产品负责人（用户本人），2026-10-01 拍板「前期先用模拟数据，要显示人多；正式页先用模拟，真实数据跟上后替换」；已书面告知虚假宣传风险（《反不正当竞争法》第 8 条）。
+   - 期限：**最晚 2026-12-31** 复核（≤ 3 个月）；真实数据接通后在后台把 `MamaBoxConfig.pulseMode` 改成 `real`（或 `off`），无需发版。
+   - 2026-10-02 扩展：卡内新增「同周悄悄话」（`GET/POST /whisper`、`POST /whisper/hug`）。mock 模式下真实悄悄话与 box_app 生成的**模拟悄悄话**（id 以 `m_` 开头，确定性哈希、不落库）混排，跟随同一个 `pulseMode` 开关；real 只出真实的。⚠️ 模拟句是「假装有人说过的话」，比模拟数字更敏感，切 real 时务必一并去掉。
+   - ⚠️ 悄悄话后端（`models/mamaBoxWhisper.py`、`services/mama_box_whisper_serv.py`、`mama_box_router.py` 与 `models/__init__.py` 的改动）是 2026-10-02 **直接改在服务器 `/opt/app/box_app` 上的，没进 git**（当时的账号无 box_app 推送权限；改前备份在 `/opt/app/box_app_bak_202610021000`）。服务器下次 `git reset --hard` 前，必须由有权限的人先把这几个文件提交进仓库，否则接口会丢。
+   - 边界：**只限这张卡**。孕期盲盒的数字（已收集、本周开盒人数）一律真实；任何别处都不得引用这里的模拟数字，前端也不得在接口失败时自造数字兜底。
+
+13. **跳其它 H5 应用 / 调第三方接口一律同源：只写相对路径 `/<slug>/`，不写域名**（2026-10-09 用户定）
+   - 背景：小程序 web-view 只放行业务域名 `mp.yizhezhe.com`，直连 `taidong.douba.top`（或任何 `*.douba.top`）会被拦；
+     首页直接 `fetch` 别的域名还会跨域。所有第三方 H5 都由 mp 前置机（8.145.39.61）nginx 反代过去，路径不变。
+   - 写法：`const XXX_URL = '/<slug>/';`、接口 `'/<slug>/api/...'`。确实需要完整地址的地方（如 `return_url`、上报 last_app）
+     用 `location.origin` 或 `new URL(path, location.origin)` 拼，**也不要手写域名**；万不得已写死时只能是 `https://mp.yizhezhe.com/...`。
+   - **新接一个应用前，先 `curl -s -o /dev/null -w '%{http_code}' https://mp.yizhezhe.com/<slug>/` 测：**
+     - 200 → 直接用相对路径；
+     - **404 → 说明 mp 还没反代这个目录**（不是「小程序白名单没加」，别等别人）。去 mp 的 `/etc/nginx/conf.d/default.conf`
+       把 slug 加进「第三方 H5 应用统一反代」那条 `location ~ ^/(...)/`（页面和 `/api` 都在目录下时一条就够），
+       再加一行 `location = /<slug> { return 301 /<slug>/; }`。改前 `cp -a` 备份，`nginx -t` 通过才 `nginx -s reload`，
+       之后对比 `mp` 和 `taidong` 两边同一路径的内容应一致，并复查 `/mama-box/`、`/mama-box-preview/`、`/api/mp/...` 仍 200。
+       ⚠️ 这台机同时跑正式站，改 nginx 前先告诉用户。
+     - 应用的页面或接口不在 `/<slug>/` 目录下（比如接口在根路径 `/api/xxx`）→ 别在 mp 上加兜底，先找该应用的会话改成目录内。
+   - 历史：2026-10-09 一次补了 `chengzhang-dangan`、`muying-xiaoxiao`、`yinger-fang`、`doudou-duihuan` 四个（备份 `default.conf.bak.4proxy-20261009222036`），
+     首页这 4 个入口同日改为相对路径（v26100906）。例外：微信 JS SDK `res.wx.qq.com` 是官方脚本，不在此列。
+
+14. **任何 H5 应用「返回首页」一律调 `wxAuth.goHome()`，禁止写死首页地址**（2026-10-09 用户定）
+   - 原因：首页地址是后台动态配置的（见第 1 节），写死 `https://mp.yizhezhe.com/mama-box/` 会把用户送回旧首页。
+     `goHome()`（`js/wx-auth.js` ⑦）先拉 `/api/mp/public/home/config` 再跳，自动续接 openid/unionid；1.5s 超时或接口坏 → 回退 `/mama-box/`。
+   - 写法：`if (window.wxAuth && typeof wxAuth.goHome === 'function') { wxAuth.goHome(); return; }`，
+     原来拼身份的写死地址只允许留作 **wxAuth 没加载时的兜底**。
+     ⚠️ `goHome()` 的身份只认 URL + sessionStorage（`identity()`）。应用若把身份从 URL 抹掉、存在 localStorage 等别处，
+     站内跳几次后回首页会带空身份 → 调 `goHome()` 前先 `wxAuth.rememberIdentity(openid, unionid)`（数胎动 2026-10-10 首个这么做）。`wx-auth.js` 用绝对地址 `https://mp.yizhezhe.com/mama-box/js/wx-auth.js` 引入。
+   - 首页带 `return_url` 跳过去的应用（档案 / 婴儿房 / 商城）返回时回 `return_url` 即可（它就是当时的首页地址）；**没带 `return_url` 时的兜底也要走 `goHome()`**，别 `history.back()`。
+   - 本仓库自己：首页内部不要用 `goHome()`（那是给别的应用回来用的）；`wx-auth.js` 里 `DEFAULT_HOME` 是唯一允许写死首页的地方。
+   - 2026-10-09 普查（48 个目录）：主返回写死 `/mama-box/`、已通知各自会话改的有 数胎动 taidong（预览版已改，正式待批）、孕检日历 chanjian-rili（10-10 已上线，复扫通过）、待产清单 daichan-qingdan、
+     体重 yunqi-tizhong、血糖 yunqi-xuetang、数宫缩 gongsuo-pinlv；laixin、laixin/youju、yunqi-nengbuchi、shengao-tizhong 已先调 goHome（写死仅兜底）。
+     新接应用前照此检查：`curl -s https://mp.yizhezhe.com/<slug>/ | grep -n "mama-box/'\|goHome"`。
+
 ## 5. 踩坑
 
 - **不要给别的应用追加 `#openid`**：部分应用自带 hash 路由（如 `/baobao-yingji`），追加 hash 会被当非法路由 → 页面未找到。身份一律走 query（`withIdentity()` 已封装）。

+<!-- 2026-10-03 创意预览（不进正式首页）：「宝宝把倒计时改了」—— 设计为每天一次的小彩蛋。
+     头图拆层同 demo/occupy（胶囊里的「67」单独用 HTML 渲染，才能做翻牌）。
+     时间线：1s 后一只小胖手从羊水囊那边伸过来 → 手指按住「67」往下拨，个位 7 滚成 6（66）→
+     手停住、冒个问号（发现不对）→ 偷偷往上拨回 67 → 手飞快缩回去 → 胶囊旁冒一句「我有点着急。」带一滴汗。
+     正式上线时按北京时间「每天首次打开首页」播一次（localStorage 记日期）；本预览页每次打开都播，并给「再看一次」。
+     ?rec=1：由 __set(t) 逐帧驱动（生成动图用）。 -->

+/* ================= 首页头图：宝宝时不时动一动小手小脚（2026-10-05） =================
+   用户：「右上角羊水袋里的小宝宝时不时稍微动一动小腿、小脚、小胳膊，缓缓地动，不要太激烈」。
+
+   ⚠️ 之前试过 AI 生成的 GIF，整张一起扭，脸型、腿型都变（见 hero-fx.js show() 里的注释），所以这里不用动图：
+      在静图上盖一张 WebGL 画布，同一张 PNG 原样画上去，只在「关节 → 手脚末端」这一小段做小角度旋转扭动，
+      脸周围是保护圈（权重强制为 0），头和身子一像素都不动。
+   · 每个阶段的关节位置手工标在 LIMBS 里（坐标 = 480×480 原图像素）。1、2 阶段是胚芽，没有手脚，不动。
+   · 节奏：每隔 2.5～6 秒随机挑一处（小腿 / 小脚 / 小胳膊），用 1.8～2.8 秒缓缓抬起再放回；
+     偶尔小腿和小脚一起「蹬」一下。角度只有 3～9 度。不动的时候不重画（不占电）。
+   · 跟 hero-fx.js 解耦：不改它，只盯 #heroStill 的 src / class —— 换阶段、淡入淡出都自动跟上。
+   · 没 WebGL / 系统「减少动态效果」→ 什么都不做，静图照常。
+   · 调试：URL 带 limbdebug=1 → 角度 ×4、动作更频繁，并把会动的区域染成蓝色，方便核对关节标得准不准。 */

+/* ================= 首页彩蛋：宝宝在肚皮底下动（2026-10-03，预览） =================
+   整个首页当成妈妈的肚皮：宝宝时不时用小脚丫 / 小拳头 / 小膝盖 / 小屁股从底下往外顶，
+   把顶到的那片内容撑成一个软软的小帐篷；滑到哪个模块，宝宝就跟到哪一屏。
+   原型见 demo/bump（那边是把整页截图当纹理扭，这里是真实页面，做法不同）：
+     · 鼓包 = 附近真实元素（叶子级的文字块、图标、图片）按离鼓包中心的远近往外撑开 + 放大 + 往外倾斜，
+       再在上面盖一层只画光影的 canvas（亮面 + 投影）。元素还是原来的元素，照样能点。
+     · 只动 transform，不碰布局；动完把元素的行内 transform / transition 原样还回去。
+
+   和点击的关系（产品口径 2026-10-03）：
+     1. 宝宝尽量不顶按钮：挑位置时，鼓包范围里只要压到小按钮 / 链接 / 输入框就换地方；
+        整张能点的大卡片（工具格、知识卡）允许顶。
+     2. 真顶到了能点的地方：第一下算「摁宝宝」—— 这次 click 在捕获阶段被拦掉，不跳转；
+        宝宝缩回去后再点就正常跳。只拦鼓包中心那一圈，点在边上照常跳。
+     3. 宝宝冒头不到 0.3 秒就点下去 = 用户本来就是要点按钮，碰巧冒出来：不拦，照常跳，宝宝顺便缩回去。
+     4. 用户在滑 / 在点的时候宝宝不出来：页面静止一会儿才顶；弹层、详情页盖住时不出来。
+
+   摁中时的反馈（一次约 1.2 秒）：
+     0ms   轻震（安卓）+ 一声很轻的「噗」+ 按出一个窝，鼓包被压扁、往四周摊开
+     80ms  稍重一震 + 更轻的「啵」，鼓包往远离手指的方向滑开、沉下去，冒一颗小 ♡
+     松手  窝 duang duang 回弹，周围的内容跟着颤几下
+     600ms 三次里有一次：旁边轻轻反踢一下（宝宝不服气）
+   ⚠️ iOS 的网页没有震动接口（微信 JS-SDK 也没有），苹果用户只有画面 + 声音。
+   按孕周分阶段，尽量贴近真实胎动（2026-10-04 用户：「尽量模拟真实的」）：
+     · 20 周前 / 没填预产期 / 已产后：不出现（这时候肚皮外面看不到胎动；没孕周就不猜）
+     · 20～25 周「小鱼吐泡泡」：小、浅、一闪就没，常常连着两下；隔 10～25 秒才一次，周数越小越稀；滑过来也不追
+     · 26～33 周「拳打脚踢」：完整版——小脚丫 / 小拳头 / 膝盖 / 小屁股，最勤（隔 4～8 秒），中途还会再顶一下
+     · 34 周起「地方小了」：很少猛踢，多是一大片慢慢拱过去（翻身、屁股），节奏放慢（隔 7～12 秒），次数不减
+     孕周来自 app.js 的 mb-preg 事件（syncPregnancy 跑完后广播）。调试：URL 带 bumpweek=24 可强制按 24 周演示。
+     · 节奏（26 周起）：有时原地「哒哒哒」带节奏连踢几拍；有时踢完不歇，旁边紧接着再踢 1～2 下
+   开关：「我的 → 隐私权限 → 宝宝在肚皮下动」，存 localStorage 'mb_bump'（'0' = 关）；系统开了「减弱动态效果」也不出来。 */

+
+   ① 换宝宝：孕周来自 app.js 的 mb-preg 事件（syncPregnancy 跑完广播，首屏一次、远程档案回来再一次）。
+      9 个阶段各一张「羊水囊 + 宝宝」整幅图：静图（首帧）先出，GIF 加载完再盖上淡入。
+      没建档 / 产后 / 事件迟迟不来 → 用第 6 阶段（原来那个 25 周的宝宝）。
+      孕囊大小 = .hero-baby 的 --k（相对原 25 周囊的倍数），CSS 里围绕同一圆心缩放、带过渡。
+      调试：URL 带 kidweek=12 强制按 12 周显示。
+   ② 羊水 + 光束：#heroWater 一张 WebGL 画布（搬自参考页 womb-water.js），在孕囊下面。
+      柔光束 + 柔和水波光影 + 悬浮微粒，宝宝区域避开（详见下面那段）。
+      不在首页 / 页面隐藏 / 头图滚出视口时停画；系统「减少动态效果」下整块不画（CSS 也隐藏）。 */

+"""夜晚模式样式生成器：读 mama-box.css，把浅色底 / 深色字自动翻成夜色，写进 night.css 的「自动生成」段。
+
+为什么用生成而不是手写：mama-box.css 有 4700 行、几百处写死的 #fff / 暖白，手写一份夜间版
+既漏得多、又会和日间版各改各的。这里只做「颜色翻转」这一件机械的事：
+  · 背景 / 边框类属性里，亮且不太艳的颜色（暖白、米色、浅灰线）→ 同色相的深色（卡片比页面底略亮）；
+  · color / fill / stroke 里，暗的颜色（正文墨色、灰字）→ 同色相的浅色；
+  · 品牌橙、工具卡的绿 / 紫 / 蓝这些高饱和色、白字、透明度低的玻璃白，一律不动。
+每条规则原样复制选择器、前面加 html.night，所以优先级比日间版恰好高一级，顺序关系不变。
+自动翻不好的地方写在 night.css 的「手调」段（在生成段之后，同优先级后写的赢）。

+用法：python3 tools/gen-night.py [mama-box.css]   改了 mama-box.css 的颜色后重跑一次。

+# 婴儿房封面补天空（2026-10-06）
+
+起因：首页「我们的家」视差缝往上滑时，原封面（nursery-day/night.jpg，1125×1500）顶边正好切在松树中间，
+树被一刀截断、上面是一块纯色。用户要求「把树上面整体调成天空，衔接过渡一下」。
+
+做法（产出 assets/img/nursery-{day,night}-sky.jpg，1125×2000）：
+1. 原图贴到 1125×2000 画布底部，上方 500 像素填原图顶部天色（白天 #F0F5F7、夜晚 #2F375A）。
+2. 用图片生成技能（tupian，模型 nano_banana_pro，9:16 2k）图生图：只补上方空白——树尖补完整，往上是天空（白天淡云，夜晚小星星），其余不变。
+3. AI 结果直接缩放到 1125×2000（实测和原图逐像素对齐，无需平移），y<600 用 AI、600–760 smoothstep 渐变、y>760 用原图像素。
+4. JPG quality 88。
+
+3D 婴儿房会话（33d6c837）以后若重新导出封面：照上面四步重做一遍，改 app.js 的 NY_COVER_V 和 index.html 的 ?v=。
+旧的 nursery-day.jpg / nursery-night.jpg 保留没删，回滚时把 -sky 去掉、CSS 里 margin-top:-136px 那条删掉即可。
