/* === 设计令牌 ===
 * design-taste-frontend-v1 原则适配原生栈：
 *  - Geist + Geist Mono（禁 Inter）；系统兜底，离线优雅降级
 *  - 单一 accent，饱和 <80%；去 AI 紫/纯黑/霓虹辉光
 *  - 去卡盒化：仅统计卡用高程（diffusion shadow，着背景色相），
 *    工具栏/目录区改 hairline 分割 + 负空间呼吸
 *  - hero 不用渐变 wash，改 accent top-rule + 极淡色相
 *  - 砍入场 stagger（"只有动画"的源头），仅留功能性动效
