/* ============================================================================
   易支付 · 全局样式（HeroUI 风格设计令牌）
   ============================================================================
   设计原则：
   1. 全部视觉参数走 CSS 变量，方便后续换主题而不动结构
   2. 明暗双主题：通过 html[data-theme="dark"] 切换，默认浅色
   3. 无外部依赖（不含 Tailwind 运行时、不含 CDN 字体），首屏零阻塞
   4. 移动端优先：收银台的绝大多数流量来自手机
