/* ==================================================================
 * 飞牛 · PC 端设计系统 v2
 * ------------------------------------------------------------------
 * 设计语言：企业级控制台（桌面端）
 *
 *   · 骨架      浅灰底 + 白色卡片 + 1px 描边，不用投影、不用渐变
 *   · 中性色    冷静的灰阶（标题深、正文中、辅助浅），彩色只用于语义
 *   · 圆角      2 / 4 / 6 / 8 四档，控件用小圆角，卡片不超过 8px
 *   · 字号      12 / 13 / 14 / 16 / 20 / 24 六档，取消半像素字号
 *   · 间距      4 / 8 / 12 / 16 / 20 / 24 / 32，8 点栅格
 *   · 投影      仅浮层（弹窗 / 下拉 / 抽屉）使用，内容区一律无投影
 *   · 品牌色    沿用平台蓝 #1677ff，与小程序 / H5 视觉统一
 *
 * 零外部依赖：不加载任何 CDN 或第三方库，字体走系统字体栈。
