  手写 CSS，无构建步骤、无外链、无 Tailwind。

  视觉约束：纯白画布 #FDFBF7、近黑 #241F1A、灰 #6E6E80、发丝线 #ECECF1、
  唯一强调色 #A5643C 只做小面积（光标、圆点、hover 下划线、图标描边）。

  动效说明：
  - .reveal 默认就是可见状态，IntersectionObserver 只负责在元素进入视口时
    追加 .is-in 触发一次入场动画。这样在禁用 JS、打印、以及整页截图（整页
    截图不会触发 IntersectionObserver）时内容都不会出现空白块；脚本会给
    「首屏已经可见」的元素跳过观察，避免淡入动画把已经可见的内容闪回 0。
  - prefers-reduced-motion: reduce 下统一关闭所有动画与过渡。
