/* ==========================================================================
   狗狗记账 · 全站设计系统 (theme.css) v5
   --------------------------------------------------------------------------
   原则：
   1. 全站只用 Bootstrap 5.3 原生组件（.btn / .form-control / .card / .table ...），
      这里统一“换皮”，页面模板里不再写 <style>，也不再发明自己的按钮/输入框。
   2. 颜色、圆角、阴影全部来自下面的 token；改一处，全站生效。
   3. 移动端优先：触屏设备输入框字号强制 16px，杜绝 iOS 聚焦自动放大。
