   配色基准（以 D691 人类拍板定论为准，2026-09-18）：
     --brand-ink #0E2350   品牌面（Hero/页脚/CTA 渐变起点，蓝黑色）
     --accent    #1D4ED8   交互面(按钮/链接) 静止态
     --accent-hover #1746B5 交互面 hover 态（加深）
   说明：D691 原文「深蓝基线 + hover 变浅」即用户本人拍下的品牌方案；
     旧规范稿 nexoflow-ui-style-compare.html（要求基线 #2563EB）已过期，不沿用。
     故本站静止态用更深的 #1D4ED8（蓝黑倾向），hover 加深到 #1746B5，
     避免整站偏「浅蓝」。品牌深蓝黑 #0E2350 用于大面积(Hero/页脚/CTA)与重点块。
   纪律：
     · 主色仅用 深蓝黑(#0E2350) + 动作蓝(#1D4ED8 静止 / #1746B5 hover)
     · 彩色仅用于语义状态/焦点（成功/警告/危险/信息）
     · 按钮一律方形圆角 6px，严禁胶囊(100px)
     · 阴影一律 navy 染，禁止纯黑阴影
