等等，我需要确认输出格式。标记必须是三个尖括号，而且每个只能出现一次。我用了 `` 和 ``，这没问题。但规则又说除了标记之外不要再写说明。那我的 `<<<END>>>` 和那段中文思考就不该出现。得把这段删掉。再重新整理一下输出，只保留 ``、HTML 内容、`` 和 CSS 内容。

现在我把这段 HTML 重新整理好，确保里面没有多余的标记和说明，只保留页面主体内容。接下来要准备页面专属的 CSS，所有选择器都限制在 `.page-faq` 作用域内，避免影响其他页面或共享样式。

CSS 从页首区域开始写。页首用深色背景做底，配上一张低透明度的氛围背景图，再叠加一层渐变遮罩保证文字可读性。标题、导语和数字小条都在这上面展开。接着是主体双栏布局：左侧是粘性目录，右侧是问答区。移动端目录会变成横向滚动的胶囊菜单，避免占用过多垂直空间。

再往下是快捷卡片和各个问答分组。分组标题带一个橙色的编号，用 flex 排列，和标题文字对齐。手风琴部分用原生的 `details/summary` 实现，自定义了展开收起时的符号变化。最后是求助卡片和底部说明区，整体都保持夜场蓝和球场绿的色彩节奏，橙色只用在关键动作和状态提示上。无障碍方面也考虑到了，`prefers-reduced-motion` 下会关闭位移和脉冲，只保留透明度变化。

整个结构从“第一步怎么走”到“遇到问题找谁”，信息密度由浅入深，适合第一次来的人快速上手。页面里也放了两张配图，一张是页首氛围图，一张是“三步走”旁边的场景图，都用了懒加载。现在这些准备就绪，直接输出即可。
