/* ═══ r74 · 首页「优势」模块重做(2026-10-12)════════════════════════════
   位置:首屏之后第二屏(整段上移到「亮点」之前)。
   版式:大标题 + 一行说明 → 通栏旗舰舞台卡「自研交易内核」→ 三张证明型优势卡(上图下文)→ 实时品种带 → 两个按钮。
   本文件最后一个加载,所有规则以 #edge 开头,只改 #edge 自己的类;edge-r40.css 与各主题层原样不动。
   撤销 = 删掉页面 head 里引用本文件的那一行(标记要整体回退,用 _bak-pre 里的两份页面)。
   卡面按官网设计体系 v1:深灰底 + 极细白色半透明边框,无传统投影;卡片不可点,所以没有悬停上浮。
   浅色不是深色反相:白卡 + 蓝调柔影,字用墨色,强调走蓝。
   圆 = 机器,方 = 人:图里的节点是圆;选项卡和品种格是人在操作的,取小圆角方形。 */
