 * uc-base.css — 零时科技 C 端 · 用户中心基础组件层
 * 来源：自 static/css/admin.css 精确抽取「C 端实际消费」的部分
 *       （全局 reset + 通用组件 + 暗色增强层），变量值 1:1 保留。
 * 目的：F-FE1 统一批（2026-09-11）解除 C 端对后台样式表的耦合 ——
 *       user_center.html 不再 <link admin.css>，后台样式调整不再波及 C 端。
 * 层叠顺序：tokens.base.css → tokens.light.css → uc-base.css → 页面内联 <style>
 * 注：原 admin.css 中 html[data-theme="light"] 分支与后台专属布局类
 *     （topbar / sidebar / trade-* / stat-card …）经核实不在 C 端生效，未收录。
