/* =========================================================================
   manuscript.css —— 投稿指南页（manuscript.php）专用样式
   · 所有选择器都以 .jg（journal guide）命名空间开头，不影响全站其它页面
   · 需要压过的全局规则：popbox.css `*{list-style-type:none}`、styles/style.css
     `*:focus{outline:none}` / `h1-h6{font-weight:normal;font-family:TuffyRegular}` /
     `p,ul{margin-bottom:20px}`、css/style.css `a{color:#444}` / `p{font-size:15px}`
   · 四刊主题色与首页 Highlights 保持一致：
     A #2c60ac；B #00a058；EITEE #da4548；BDM #946fb2
