/* 孕期专题页共用渲染（2026-11-01）
|
||
* 用户：「其他妈妈也在搜」剩下的问题都做成专题页，UI 和文字参考「叶酸、DHA、铁、钙要不要补」（topic/buji）。
|
||
* 每个专题目录只放 index.html（内联 window.TOPIC 数据）+ img/hero.webp，版式全在这里和 article.css。
|
||
* 区块 type：cards 卡片矩阵 / timeline 按孕周横向条 / vs 两栏对照 / list 清单 / steps 步骤 / doc 找医生 / check 自查。
|
||
* 自成一页：不引 app.js；返回回 ../../；工具跳转走 ../_shared/tools.js（同源路径 + search + hash）。
