/* ==========================================================================
   全站页面视觉规范（后台 + 客户端内容区）—— 只改样式，不动结构与脚本
   加载顺序：form-system.css / feedback-system.css 之后（见 panels/styles.blade.php）

   作用域 .content-body；用 :where() 包住作用域，不额外抬高优先级，
   各页面自己写的样式（page-style）仍然生效。
   已单独调整过的页面跳过：短信测试（.cr）、短信服务表单页（.sp-page）、双向短信（.fx2-chat-shell）、登录注册（.au-page）
   圆角沿用 global-border-radius-20px.css；按钮 hover 不加阴影 / 位移（no-hover-shadow.css 项目约定），只降透明度
