/**
 * 三汇咨询向导 v2 样式（增长诊断 Modal + PC 悬浮 FAB + 移动条三按钮）
 *
 * 设计要点：
 * - 全部使用全新 sanhui-dx- / sanhui-consult-fab 类名，与旧版问题容器的
 *   「display:none + .is-active」双轨显隐地雷（审计 §4）彻底隔离；
 *   本文件加载于所有样式之后，负责覆盖一切。
 * - 显隐唯一机制 = hidden 属性；下方兜底规则保证 author 级 display 永远压不过 [hidden]。
 * - 品牌色沿用 sanhui-frontend.css 的 :root 变量（深海军蓝 + 金 + 白）。
