   site.css —— 2026-09-24 方案 A「一封长信」改版的全站组件
   --------------------------------------------------------------------------
   叠在 style.css + sixianghui.css 之上用（页面 body 都带 .sh，复用私享会页那套
   Eden 版式：sh-hero / sh-band / sh-sec / sh-h2 / sh-prose / sh-quote …）。
   这里只放私享会页没有的：产品行、章节进度条、抽屉 / 弹窗、关于我时间线、
   私享会收尾卡、板块页、产品详情页（.pd）。类名一律 st- 前缀。
