/* ==================== BUG-1 修复（2026-09-06 修订） ====================
   切到 Agent 视图时隐藏经典欢迎页浮层。
   .welcome-page 直接挂在 <body> 下、不在 #classic-solution 内，原
   "#classic-solution{display:none}" 无法隐藏它；且其显隐由 welcome-script.js
   用内联 style.display 控制，故必须用 !important 覆盖内联样式。仅在
   body.view-agent 下生效，classic 视图完全不受影响。
   修订：#demo-selector-modal 从本规则移除——它是右上角「体验」按钮的弹窗，
   原规则会把按钮点击设置的内联 display:flex 一并压掉，导致 Agent 视图下
   顶部「体验」完全无响应；现允许其在 Agent 视图正常弹出（案例点击后由
   welcome-script.js runDemo 切回经典视图再跑标准匹配）。 */
