/*
 * hufu-theme/word-universe —— 派生文件，不要手改。
 *
 * 由 tools/build-word-universe.py 从仓库根目录
 * HUFU_设计语言文字宇宙_离线单文件版.html 生成。改原型后重跑脚本。
 *
 * 与原型的主要结构性差异：
 *   1. 所有选择器都加了 .hufu-cosmos 前缀（token 也随之只在这一节生效）；
 *   2. position:fixed 改成了 absolute，浮层相对本节而不是视口定位；
 *   3. 底色改读主题的 base（见文件末尾的容器规则）。
 * 完整清单见 tools/build-word-universe.py 头部。
 *
 * 老坑提醒：改完记得抬 block.json 的 version —— style.css 的 ?ver 取的
 * 是 block.json 里的 version，旁边的 style.asset.php 会被静默忽略。
