/* 升学页（v5，2026-11-01；site_design\网站_v5要求.md 第四节）。只在 guides.html 引入，类名都以 gd- 开头，site.css 不动。
   颜色、字号、间距只用 tokens.css 的变量（二维码底色除外，见最后一节）。
   动画：轻、慢，每段不超过 5 秒，播完停在终态，不循环。
   - 元素的基础样式就是终态；动画只写「从哪里来」（keyframes 只写 from 或前半段）。
   - 进入视口再播：<html> 有 .gd-js 时，没进视口的 .gd-anim 里的动画先暂停（停在开头那一帧），脚本加上 .is-in 再播。
   - 系统设了「减少动态效果」：site.css 统一关掉动画，这里的动画也只写在 no-preference 里，页面直接是终态。 */
