 * 一麦生花 Brand Site V5 · 官网新板块
 *
 * 作用域：只在 .brand-home 页面内生效。pricing / login / report 不引入。
 *
 * 配色策略（2026-09-01 定）：
 *   整页浅色蓝白，与 app 内部一致，避免官网到工作台的视觉断裂。
 *   数据面板局部用深蓝渐变，直接复用 app.css 的 .geo-insight 语言：
 *   深蓝渐变实底 + 白字 + 关键数字暖黄 #FDE68A。
 *   深色面板全站只出现 2 处（Hero 信号面板 / 能力矩阵监测格），不泛滥。
 *
 * 形状规则沿用 V4：控件 10px · 卡片 18px · 大面板 22px。
