/* ==========================================================
 * 文件: quant-ai-dark/landing-s39.css
 * 版本: 0.1.0 · 更新: 2026-10-23 · 作者: Claude（为李泓锐）
 * 用途: 落地页第 3–9 屏：左文字、右「能读的」数据面板；3D 焦点全部是 CSS 3D（不加 WebGL）
 *   视觉延续第 1、2 屏：近黑底、冰蓝点缀（--violet 在落地页里就是冰蓝 #8fb8ff）、白字三档透明度
 *   表格沿用第 2 屏的 .board 样式；锁定态沿用 shared/member-ui.css 的 .locked-block，这里只调落地页的配色
 *   动效：立方体慢转、波浪慢起伏、悬停高亮；减少动效时全部静止
 * ========================================================== */
