/* ==========================================================================
   发布出来的只读站点  —  样式
   --------------------------------------------------------------------------
   功能模块：只读站点（/s/<短码>/）的结构与语义层，定义读者侧观感——
   浅色纸感、衬线标题、顶部导航 Home / 分区、卡片网格、正文行宽收窄。
   加载顺序（依据 DESIGN.md §4 的契约，顺序不能改）：站点页依次加载
   site → apple → terminal → polish → experience。本文件排在最前，负责定
   结构与本页语义 token（--paper / --ink / --site-primary 等）；后面的
   apple / terminal 换肤层再据此覆盖。选用暖纸白 + 深墨的浅色取值，是为了
   面向读者的纸面观感，而不是工作区的深色终端配色。
