/* ============================================================
   jingsi 主题 · 仿 book.tinynews.org 静思书屋（Django + Bootstrap 5 极简书站）
   设计规范（参考站首页/详情 HTML inline style + static/wait.css、media.css 实测）：
   - 主青蓝 #206487（站名/标题/链接/搜索钮/下载按钮组）；辅助紫 #62597C（次按钮/提示条）
   - 页面底 #F6FAFE（极浅蓝全页）；面板底 #EBEEF3（分节大容器/面包屑/胶囊大量使用）
   - 正文 #181C1F；分页灰斜体 #7c7575；星标金 #FDE16D；免费绿 #198754；价格红 #dc3545
   - 形制：无 topbar 无侧栏无轮播；品牌行（斜体站名+大搜索框）+ 极简横导航
     + 斜体分节标签 + 浅蓝大容器白卡封面流（3:4 竖版书封）+ 文字流分页
   注意：pay-* 弹窗类名是 JS 契约不可改；JS 会 inline 设 display:block，
        弹窗内按钮必须自带 width + margin:auto 居中（勿依赖 text-align）
