   alltools.html —— 单个工具（功能子系统）的详情页 / 新版
   --------------------------------------------------------------------------
   页面本身不带功能：所有按钮都深链到业务系统，用户登录后才真正使用。
   所以举证责任全在页面上——Before/After、演示、参数表、评价是主线，
   不是配菜；CTA 在每个板块结尾都要出现一次。
   只有本页在用，不引用也不被别的页面引用。
   顺序：Hero → 信任条 → 粘性 tabs → How it works → 能力分块（zig-zag）
        → 参数表 → 场景 → Before/After 画廊 → 评价 → 定价摘要 → FAQ
        → 相关工具与教程 → 底部 CTA

   1. 去掉空段落造成的大块空白

   3. 宽度保持原样，不做限宽
   4. H3 小标题加左侧色条，层级更清楚
