   分区（顺序即层叠顺序，不要打乱）：
     1. TOKENS      —— 唯一真源：颜色 / 字体 / 字号 / 间距 / 圆角 / 阴影 / 动效
     2. BASE        —— reset、排版、容器、区块、无障碍兜底、颗粒
     3. COMPONENTS  —— 导航、按钮、卡片、表单、页脚等全部组件
     4. UTILITIES   —— 柔光背景、媒体框、进场、扫光、分隔线

   硬纪律（改前先读 design/visual-direction.md §9.2）：
     · 组件里不写裸 HEX，颜色一律取第 1 节的变量
     · 玫瑰主色 --color-rose 只做装饰，任何文字都不用
     · 所有阴影基色为暖棕 rgba(var(--glow-shadow), …)，alpha ≤ 0.10
     · .glass 元素之间不得互为祖先 / 后代
