/* ============================================================================
 * ztncui · 2026 双主题设计系统
 * ----------------------------------------------------------------------------
 * 两套风格，一套组件，右上角一键切换（不刷新）：
 *   [data-theme="aurora"]  极光玻璃 · 轻盈通透（默认）
 *   [data-theme="ivory"]   米白编辑部 · 杂志感、发丝线、衬线数字
 *
 * 说明：
 *  · 仍然跑在现有 Bootstrap 3 的 DOM 上，但 **外壳（顶栏/侧栏/首页/登录）已重写**，
 *    不再依赖 Bootstrap 的 navbar / panel 外观。
 *  · 全部尺寸/颜色走变量，切换主题只换变量，不动结构。
 *  · 旧页面里的内联 <style> 由第 9 节的覆盖层统一压住，逐页迁移后删掉覆盖。
