/* ---------- 首页 hero：滑动浮现（JS 读滚动位置驱动，两种模式） ----------

   两种模式，由 main.js 里一个开关 HERO_SPLIT 切换，CSS 这边只是两套样式：

   ① 丝滑模式（默认，HERO_SPLIT = false）
      整块当成一个元素：透明度 + 上浮一起连续变化，中途没有任何卡点。
      观感等同于之前那版 animation-timeline: view()，区别是进度由 JS 算，
      可以读出来验证（那版跑在合成器上，永远读不到真实进度）。

   ② 分层模式（HERO_SPLIT = true）
      标题 → 引言 → 副题依次浮现，各读自己的变量。
      层次更清楚，但中间态会出现「标题已经清楚了、引言还虚着」的割裂感，
      不够「整块丝滑」——这就是为什么默认关掉。

   两种模式都只是「读」滚动位置来算透明度，不接管滚轮、不吸附、不改滚动速度，
   手感和原生滚动完全一致（和被否掉的 scroll-snap 有本质区别）。

   ★ 想调「浮得快慢」：main.js 里 paintHero 的 from / to
   ★ 想调「浮起多少距离」：本文件下面的 30px（丝滑）/ 26·20·14px（分层）

   兜底：只有 JS 真跑起来才会给 .hero 加 .hero-reveal；
   脚本被禁用、报错、或用户开了「减少动态效果」时都不加，
   文案就是满不透明满位移——绝不会因为动画停在起始帧而消失。 */

   配色跟「设置球」的色相走：三处颜色都写成 hsl(var(--hue) …)，
   --hue 由 main.js 的 applySettings 与 baseof 的防闪脚本写入。
   亮度刻意保持很高（84~94%）——这里压着深色动态壁纸，
   颜色一深沉就糊成一片；低亮度只用来染色相、不用来压暗。
   ★ 想让它更明显/更克制：调下面的饱和度（62/78/38）与亮度（92/91/84）。
     饱和↑ 更艳；亮度↓ 更深但更容易看不清。 */
