 * Foliage v1.0 — spa.css
 * SPA 用户中心专用样式层 (Vue 3, 11 路由)
 * 设计原则:
 *   - 不重复 components.css: 复用 .btn / .card / .badge / .grid 等
 *   - 增量提供: SPA 专属布局/动效/可视化(KPI/Sparkline/Timeline)
 *   - 配置驱动: 0 hardcode, 全部走 tokens.css CSS 变量
 *   - 双主题: Dark (默认) + Light 通过 [data-theme="light"] 切换
 *   - 响应式: 1024px 断点 (与 base.css 对齐)
