   麒麟智投 Kirin Focus — 官网样式 v2.1（深藕荷色版）
   设计方向（依据 KIRIN_WEBSITE_ENG_DESIGN_BRIEF_V1.0 §5）：
   Institutional AI · Decision system · Night research desk · Quiet luxury
   - 深藕荷底色：紫藕灰阶铺底 + 藕荷强调 + 淡紫罗兰高光，低饱和
   - 底色整体提亮（原近黑 #070B13 → #241D2E），保留深色气质但去除压抑感
   - 层级靠字号与字重，不靠花哨色块
   - 少阴影、细边或纯留白分区；模块间呼吸感强
   - 无外部字体 / CDN 依赖，系统字体栈
   ============================================================ */
